I quote from the D programming language specification:
"Templates cannot be used to add non-static members or functions to
classes."

I guess that this cannot be done because the compiler will have problems to
decide if a method should be virtual or not.
Can we add final methods to a class? I can't see a reason why we shouldn't.

e.g.:
class C
{
template insideC(T, U)
{
final func(out T a, in U b) {a = cast(T) b;}
}}

instance insideC(int, float), insideC(float, int), insideC(byte, bit);

I realized that what I've written is nosense...
What I meant is a way to provide a quick method to add methods to a class
using templates. In the example you see a kinda anonymous template instances
(to be accessed as: C c; c.func(12, 12.0);).
But maybe it doesn't fit well in the language.

You can add methods, they'll just need to be static.
