Is it possible, using templates, tuples, or some other mechanism, to

For example, I'd like to be able to do something like...

and so forth.
Yes, with a small hack.

Hello Nick,
So...is there any trickery I
could do so that SubFoo!(sam) and SubFoo!(sam, human) would
resolve to the same subclass of Foo?
Make a SubFoo!(char[] s) that does
an if-specific syntax.
Thank you for taking the time downs,

Anytime.

I thought about the idea of just creating the code and mix it in, but now I
can see why I failed at that: Your code is kind of read-only to me, for now,
because I need to change it a bit to accept an array instead of seperat
indices.
Wouldn't it be nice if it worked

I do agree in this case. I just don't like it when Tango is proposed as an
alternative and the existence of a perfectly valid Phobos solution is ignored.
