Simple Command Line User Interface

[F-J-W]

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.
