Parameterized template value parameter

[Yuxuan Shui via Digitalmars-d]

So I was trying to make my template take a value parameter, whose 
type is also a parameter to the template. e.g.:

     template A(Char[] str, Char);

But dmd complains about 'Char' being undefined. I have to write:

     template A(Char, Char[] str);

Which is inconvenient, because now 'Char' can't be deduced by the 
compiler.

Can we make the first case work?
