Instead of storing the argument number in the znode of the parameter
list, store it in fcall->arg_num. This mainly cleans up the parameter
parsing code, which previously had to duplicate all rules (this
becomes more excessive as more features are added, e.g. named params
would already require a minimum of 14 rules...)
Fixed recognition of the operator
Added opcode, still doing multiply instead of pow()
opcode now always returns int(42)
The right answer, but always a float
Yanked code from pow() implementation.
Should not handle negative long as exponent ourselves
Added test cases from pow()
Moved precedence higher than '~'
Added GMP operator overloading
Added ZEND_ASSIGN_POW (**=) operator.
Added pow() as a language construct.
Adjusted test cases for changed precedence.
Reduced pow() to shell function around ZEND_API pow_function()
Reduced test case to only contain edge cases
Added overloading test case
Moved unary minus above T_POW
Revert "Added pow() as a language construct."
Bad bad bad idea.
This reverts commit f60b98cf7a8371233d800a6faa286ddba4432d02.
Reverted unary minus behaviour due to previous revert.

They make no sense as constants are not allowed to be arrays.
And as just properties are allowed to; no problem, we still don't
need operations on any constant array.
* The fetch_type and check_ns_name parameters of
zend_resolve_class_name were unused and are now removed.
* ZEND_FETCH_CLASS_GLOBAL is no longer used (no code actually
checking for it).
* The checks for usage of "namespace" as class name were
unnecessary as that situation can't occur anyways.
This is just an intial merge. It does not yet make generators and finally
work together.

foreach only allowed variables to be traversed by reference. This never
really made sense because
a) Expressions like array(&$a, &$b) can be meaningfully iterated by-ref
b) Function calls can return by-ref (so they can also be meaningfully
iterated)
c) Iterators could at least in theory also be iterated by-ref (not
sure if any iterator makes use of this)
With by-ref generators the restriction makes even less sense, so I removed
it altogether.
If yield is used in an expression context parenthesis are now required.
This ensures that the code is unambiguos.
Yield statements can still be used without parenthesis (which should be
the most common case).
Also yield expressions without value can be used without parenthesis,
too (this should be the most common case for coroutines).
If the yield expression is used in a context where parenthesis are required
anyway, no additional parenthesis have to be inserted.
Examples:
// Statements don't need parenthesis
yield $foo;
yield $foo => $bar;
// Yield without value doesn't need parenthesis either
$data = yield;
// Parentheses don't have to be duplicated
foo(yield $bar);
if (yield $bar) { ... }
// But we have to use parentheses here
$foo = (yield $bar);
This commit also fixes an issue with by-ref passing of $foo[0] like
variables. They previously weren't properly fetched for write.
Additionally this fixes valgrind warnings which were caused by access to
uninitialized memory in zend_is_function_or_method_call().
Generators are now automatically detected by the presence of a `yield`
expression in their body.
This removes the ZEND_SUSPEND_AND_RETURN_GENERATOR opcode. Instead
additional checks for ZEND_ACC_GENERATOR are added to the fcall_common
helper and zend_call_function.
This also adds a new function zend_generator_create_zval, which handles
the actual creation of the generator zval from an op array.
I feel like I should deglobalize the zend_create_execute_data_from_op_array
code a bit. It currently changes EG(current_execute_data) and
EG(opline_ptr) which is somewhat confusing (given the name).
Keys are yielded using the
yield $key => $value
syntax. Currently this is implemented as a statement only and not as an
expression, because conflicts arise considering nesting and use in arrays:
yield yield $a => $b;
// could be either
yield (yield $a) => $b;
// or
yield (yield $a => $b);
Once I find some way to resolve these conflicts this should be available
as an expression too.
Also the key yielding code is rather copy-and-past-y for the value yielding
code, so that should be factored out.
If the generator is used as a coroutine it often doesn't make sense to yield
anything. In this case one can simply receive values using
$value = yield;
The yield here will simply yield NULL.
Yield now is an expression and the return value is the value passed to
$generator->send(). By default (i.e. if ->next() is called) the value is
NULL.
Unlike in Python ->send() can be run without priming the generator with a
->next() call first.
