Hi!
I wrote a small patch that enables this kind of syntax in PHP:
foo()();
What it means is that if foo() returns callable value (which probably
should be function name or closure) then it would be called. Parameters
and more than two sets of () work too.
Of course, this is mostly useful for doing closures, and that was
primary drive for implementing it - to make working with closures and
especially function returning closures easier.
What does not work currently is $foo->bar()() - since it is surprisingly
hard to tell parser it's not {$foo->bar}()() - which of course is not
what I want to do.
The patch is here: http://random-bits-of.info/funcfunc.diff
What do you think? If somebody has better idea btw - maybe make
something like {foo()}() - and make that work for any expression inside
{} - that might work too. So, what do you think?
