Hi, I’m confused by the syntax, when I read it, I think to myself “I know this, this is just a method call… oh wait, it’s actually a callable”. It really makes my head hurt.

Yes, I can see how that could be confusing. The current syntax is chosen to be a subset of the partial function application proposal. However, I would also be happy with some other syntax that makes it clearer that this is acquiring a callable and not performing a call.

Hi, several other syntaxes have been proposed to consideration in the PFA thread, and I wouldn't want to start new bikeshedding here; is there a place that would be more appropriate to gather the possibilities (like a kind of updatable list)? Thanks,

I am much more into advanced features of PFA, but is this case why not just use the & operator for "function reference" like C/C++? It is well known and solves the ambiguity with method/function call. $fn = &$this->myFunc; $fn = &myFunc; $fn = &Foo::myFunc;
