Wonderful! So it's just a scope issue and not a "can't do that" issue! 
Although it would seem that the compiler 'should' be able to identify a 
different kind of ta, I can't expect too much of it and the D compiler is 
much more powerful syntax-wise than other language compilers.

I confirm that the following outputs "s1" as expected with the function call 
inside the template having the dot added in front:

string ta(string s) { return s ~ "1"; }
template ta(string s) { enum ta = .ta(s); }
void main()
{
    import std.stdio;
    writeln(ta!"s");
}
