Implicit Function Template Instantiation (IFTI) Question

[jmh530]

When using a template with multiple functions within it, is it 
possible to access the underlying functions directly? Not sure I 
am missing anything, but what works when the functions are named 
differently from the headline template doesn't work when the 
functions are named the same.

import std.stdio: writeln;
import std.traits: isFunction;

template foo(T) {
     void foo(U)(U x) {
         writeln("here0");
     }

     void foo(U, V)(U x, V y) {
         writeln("there0");
     }
}

template bar(T) {
     void baz(U)(U x) {
         writeln("here1");
     }

     void baz(U, V)(U x, V y) {
         writeln("there1");
     }
}

void foobar(T)(T x) {}

void main() {
     foo!int.foo!(float, double)(1f, 2.0); //Error: template 
foo(U)(U x) does not have property foo
     writeln(isFunction!(foo!int)); //prints false, as expected 
b/c not smart enough to look through
     writeln(isFunction!(foo!int.foo!float)); //Error: template 
identifier foo is not a member of template 
onlineapp.foo!int.foo(U)(U x)
     writeln(isFunction!(foo!int.foo!(float, double))); //ditto

     bar!int.baz!(float, double)(1f, 2.0); //prints there1
     writeln(isFunction!(bar!int.baz!(float, double))); //prints 
true

     writeln(isFunction!(foobar!int)); //prints true
}
