No, that is overriding. Overloading is having several methods with the
same name taking different number of parameters or parameters of
different types.
module test;
mixin template Foo ()
{
void bar (int i) {};
}
class Bar
{
void bar () {};
mixin Foo;
}
void main ()
{
auto bar = new Bar;
bar.bar(4); // line 17
bar.bar();
}
The above code results in these errors:
test.d(17): Error: function test.Bar.bar () is not callable using
argument types (int)
test.d(17): Error: expected 0 arguments, not 1 for non-variadic function
type void()

Have you taken a loot at Scala& traits already? It would be a great
starting point.
Scala's traits are great! Implicits in Scala are quite interesting too.
Also, Haskell typeclasses
I wonder if D can have part of Scala traits functionality with mixins?
You can't use D template mixins to add methods that will overload existing
methods.
