This code works.
string attribute(string, string s) { return s; }
//@attribute("target", T) void func(string T)() {}
template func(string T)
{
@attribute("target", T) void func() {}
}
void main()
{
alias f1 = func!"a";
alias f2 = func!"b";
pragma(msg, __traits(getAttributes, f1)); // "a"
pragma(msg, __traits(getAttributes, f2)); // "b"
f1();
f2();
}
