I think that is one of the strongest reasons not to implement something
actually. If there is a way to do something in a clear and concise
syntax, adding an alternate less clear syntax that isn't immediately
obvious to everyone simply obfuscates the language.
Fair point, although as I stated this one is obvious to me.
The other fatal blow to a feature like this is that it would be quite a
bit slower to compile and execute than the longer form because we now
can't simply do a single hash lookup in the function table when we see a
function. We first have to walk up the tree of objects to see if there
is a method with this name, and if there is no method, then we assume it
is a straight function call, unless of course there is a __call()
method, then what? Way too many gotchas here.
Hadn't considered __call() possibilities, and I didn't think the
performance hit would be too great but I'm the first to admin I don't
know the innards of PHP particularly well yet.
