THANK YOU BOTH REECE AND DANIEL :) (!!!!!!!!!!!!!!!)
That fixed it.
What is STRANGE is that "sometimes"
bind(Base::ReturnAString) works
ironically, I have about 40 calls that use that syntax that work just
fine.
I noticed in the docs, when you have a inline functor, the docs use
> bind(Base::ReturnAString);
But when you have something that was not inline (??) you use:
> bind(&Base::ReturnAString);
I was never clear on when you and when you do NOT use the "&" with the
bind() syntax.....
I will convert everything in my "real code" to using the & always.
Question:
Does anyone know when you should and should not use the & in a bind
call? Or is this is compile time checking hole that exists due to the
mechanisms bind relies upon?
OR
Am I a complete idiot?
(I find it important to always hold open this option as a possibility in
everything)
