Is there any way to get a string representing a function's

myself using reflection but it might not be 100% verbatim so 
wanted to know if there's anything built in?

   foreach (m; __traits(allMembers, T)) {
     alias member = __traits(getMember, T, m);
     string signature = // Call some function to get "member"'s
signature as a string
   }

typeof(&func).stringof should do it:

    void bar(string s, ref Foo!int i) {}
    void main()
    {
        writeln(typeof(&bar).stringof);
    }

prints: void function(string s, ref Foo!int i)

That does the trick - thanks.
