Any ideas on how this could be done?
My first idea is to have Dispatch take an alias parameter, and
see if it's useful for anything:
struct Dispatch(alias Fn, Base...) {
static auto opDispatch(string name, T...)(T vals) {
return Dispatch!(Fn, Base, name).init;
}
alias _get = Fn!Base;
alias _get this;
}
// join a list of stuff with _ between each element.
template join(T...) {
import std.conv : to;
static if (T.length == 0) {
enum join = "";
} else static if (T.length == 1) {
enum join = T[0].to!string;
} else {
enum join = T[0].to!string ~"_"~join!(T[1..$]);
}
}
unittest {
assert(Dispatch!join.A.B.C == "A_B_C");
}
No idea what to use it for, but it's kinda nice, I guess. Very
generic, too.
