is there any way to determine if an identifier is a template, and how many parameters it has?

i'm doing a multimethods kind of thing to see if you can simulate virtual template functions...

oh i figured it out, is(Templ) returns false and is(Templ!(int)) returns true
 if Templ takes one type argument

Note there are other types of template parameters.
I don't think the check above will catch these templates:
template Templ(int x) { ... }  // or float or string or ...
or
template Templ(alias x) { ... }
