How do you call a function which name is a variable?

I am trying to use this syntax to call a function "$name"(). I know this works for methods, but I do not if there is a way to do it with functions from a module.

I have tried this => sub b(){say "b";}; "b"();, but it does not work.

Any idea?

@sena_kun has answerd me via Perl6 IRC channel, and it looks like the correct syntax would be: sub b(){say "best" }; ::('&b')();.

As you can see that looks like "magic", so instead of that, @sena_kun has told me this more comprehensible way: sub a {1.say}; sub b {2.say}; my @a = &a, &b; for @a -> &f { &f()}
