Though, it's not clear to me wy the one requires casting the 
pointer type and the other doesn't.

Because typeof(&f1) == void function(S)

Right. I didn't modify the alias declaration when I took the 
functions out of the struct. I saw the immutable in the error 
message and thought that was the problem.

alias Func = void function(S);
