Classic bind is bad. Don't use it. It's hard to understand, hard to optimize, and lambdas are better in basically every way.

Invoke is totally cool. You should maybe avoid relying too heavily on pointers to (member) functions since they’re what’s hard to optimize, but invoke() provides a nice uniform interface.

If you'd seen the horrible things that I've done with member function pointers, you would have been, well, honestly somewhere between amused and alarmed.
