What if bind is lexical (that is, does it preserve the value of count or keep a reference)? If it’ s lexical, it’s close enough to my understanding of what a closure is.

I was trying to make your usage scenario work. You are binding, then calling. I suppose you want to pass the bound functor to a function and that’s why you are trying to deduce the type?

Bheesh

I’m just trying to bind a parameter now, and call the functor later.

Can you really simulate a closure with bind? I’m no closure expert, but how is bind( hello, count)(); any different from hello( count ); ?

The way I see it, the only practical use for bind is to pass it into another function template, such as for_each. That way, the compiler deduces the template parameter, and you don’t have to worry about the complicated type of the bind functor.

try:
bind( hello, count )();
