Bug description: Calling a function on a newly created object doesn't work
Description:
------------
Calling a function on a newly created object requires saving the object to
a variable. Script that clarifies what I'm trying to say:
class C
{ public function __construct() {}
public function f() { return 1234; }
};
$y = (new C())->f();
print($y);
The above doesn't work. However, it does work if you replace the
penultimate line with
$x = new C();
$y = $x->f();
If we add parentheses around the $x, i.e.
$y = ($x)->f();
then it still doesn't work. This and bug report #9587 indicate that the
actual underlying cause is that object-valued variables are implemented,
but object-valued expressions are not.
Although the "this is not a bug" comment on the above-cited bug report
#9587 did not include a rationale, it's difficult for me to decide whether
it applies here as well; maybe this bug report should actually be a feature
request? Personally, as a PHP rookie but Java veteran, I would say that
object-valued expressions SHOULD work, and they DON'T, therefore it's a
BUG.
Thanks!
Reproduce code:
---------------
class C
{ public function __construct() {}
public function f() { return 1234; }
};
$y = (new C())->f();
print($y);
Expected result:
----------------
1234
Actual result:
--------------
Parse error: parse error, unexpected T_OBJECT_OPERATOR in c:\path\test.php
on line 5
