Hello. I just want to find what is exactly the difference between:
alias _ = void function(int);
alias void _(int);
Because it's seem that the latter can't be used in the declaration of an array (eg: _[] ...).
I think the first is a pointer to function and the second is a function type itself but I'm not sure.
Regard.

yes this is correct. To declare a function type using the first form is also possible:

    alias TF1 = void(int);
    alias void TF2(int);
    static assert (is(TF1 == TF2));
