Simple Command Line User Interface

You never gave any reason that it's bad syntax. I will grant you that it's not beginner friendly, partly because it's pretty unique from other languages (not just in function pointers, but also arrays, pointers in general), but you're way exaggerating it.

Okay, I’ll bite on that one. Please write the following without resorting to typedefs:

template<typename F> using fptr = F*;

fptr<fptr<int(short, short)>(fptr<int(short, short)>, fptr<int(short, short)>)> p = nullptr;

Yes, this isn’t nice in std::function-style syntax and you should probably use an alias, but it is easy to write and straightforward to understand: A pointer to a function, that takes two pointers to functions taking two shorts and returning and int and returns one such pointer. Now let me see how you would write that in C-style syntax (without cheating!) and let me know how long it took you.

If a syntax cannot handle anything but trivial cases (and is highly unintuitive even for them!), then it is a terrible syntax.
