For hand-written code, I think the combination of "lambda" and "class"
have the potential to (almost?) eliminate the need for "function" and
its relatively confusing semantics. I've been looking through my code;
lambda and even the simplest class (instance private, zero
inheritance) would cover almost everything as drop in replacements. A
few situations would need very little reworking to use lambda and
class and as a result would be better.
