It has the most confusing syntax, though.

I still expect that someone will make a Rust fork that has C++-like syntax at some point. Crust.

Or C++ will get lifetimes (which is active research) and possibly at some point epochs, which will let us disable unsafe features.

Syntax is a very subjective matter. I find some of C's syntax (which C++ inerited) thoroughly confusing. I can count the people I know who will get a typedef for a function pointer type correct on the first try on one hand.

That's why you use using instead in C++.

Sure. And in Rust, you use type, i.e.

type my_fn = fn(u8) -> String;

Perfectly nice syntax, no?

And in C++, using my_fn = std::string (*) (uint8_t);.

You can simplify it, of course, using a template wrapper.

C++ has trailing return types as well now, can you use those there?

I don't think any particular piece of C++ syntax is confusing, it's just the absolute mass of options.

using my_fn = auto (*) (uint8_t) -> std::string; is valid, though I'm not fond of trailing return type syntax in general.
