From Bjorn Karlsson's book, P297...

Why does the assignment LHS need to be wrapped in var()?
Because operator= must be a member function.
Nope, still not getting it! Stop me when I err... if_then_else_return(...) defines a unary functor it_then_else_return(...)( value) evaluates that functor, and returns what? Some type of integer I think? So doesn't the assignment simply perform assignment of an integer, by copy? And that doesn't need operator= to a member of anything? Thanks - R.
