Still fascinating how Smalltalk implements if/then/else. Basically it goes like this (in pseudo-Swift):
class BooleanClass {
void ifTrue(_ trueHandler: () -> Void, else falseHandler: () -> Void)
}
class TrueBooleanClass {
void ifTrue(_ trueHandler: () -> Void, else falseHandler: () -> Void) {
trueHandler()
}
}

Proof-of-concept for how one could implement Objective C's target/action paradigm in a static fashion in C++. Basically, the GeneratedWindow class would be what your UI builder (like Interface Builder) generates. Button would be in your application framework. ViewController and the main() function would be how you'd then use them.

You can specify the underlying name for a C function the linker/compiler should actually use. If you use an existing
function's name, it will just let you refer to it with your prototype's name. If you define the function, it'll give
it that name. It even complains if a function of that name already exists. Tested with clang on a Mac, but AFAIK also
works in GCC. You can even use special characters in your function names, like you can do in assembly.
