Just to be clear -- I realize I could just have used unaryFun!f here
(or just f, for that matter). The usage case was actually currying. I
used "f(x,a)" as a compile-time argument to the kind of template that
we discussed earlier. And the reason I tried that was that this didn't
work either:
import std.functional, std.stdio;
int f(int x, int y) {return x;}
void main() {
alias unaryFun!(curry(f, 2)) g;
writeln(g(3));
}
At that point, the only thing that worked was using a lambda. And, as I
pointed out, with the nested templates, that didn't work either.
Seems like the language (or the stdlib) is resisting my efforts at
every turn here. Perhaps I should just write out those for-loops
redundantly, rather than using templates ;)
