Closures were an integral part of Smalltalk's design.

And functions as first class citizens is not a particularly high bar. I mean, C has higher order functions.

I'm excited to use higher-order functions in C someday :)

You can do that now. Higher-order functions are simply functions that can take other functions as parameters or return them as results. C has been able to do that since forever. It's not something fancy: pretty much every programming language has something along these lines.

What is rarer is closures, but that's a different concept. You can have higher-order functions without having closures.

Haha - I'm simply stating that I'm excited to do it and not for it to be possible :P
