Lexical anonymous functions would be enough for me. If these proposed
lexical anonymous functions could automagically bind themselves
to an instance's $this when called from within an object's scope (so as to
act
as virtual methods), that would be grand.
I agree - I don't need closures, but anonymous functions would be great.
Perhaps a very minor point, but using create_function requires that the code
is an executable string. From a maintainability standpoint, this is a
little weird since it won't be syntax-highlighted etc. (Again, very very
minor).
Question: If lexical anonymous functions were added, could this be used with
preg_replace and the 'e' modifier?
So instead of:
preg_replace('/some_pattern/e', 'base64_encode($0)', $someVar);
We could use:
preg_replace('/some_pattern/e', function ($matches) {
return base64_encode($matches[0]);
}, $someVar);
I'd love this.

Hi. I usually just lurk this list but I wanted to express my support for
the
idea of anonymous functions as a lexical construct. I think that would be
a
dandy addition. That said, I don't think that there is any need to support
closures, which in my mind represent a rather fundamental language view
which
is at odds with PHP's traditional variable scoping. I think closures are
fantastic but only in languages which take that particular variable
scoping
view from the outset. Lexical anonymous functions would be enough for me.
If
these proposed lexical anonymous functions could automagically bind
themselves
to an instance's $this when called from within an object's scope (so as to
act
as virtual methods), that would be grand.
Sorry for the noise,
boots
