This worked:
```d
import std.functional;
import std.stdio;
// Overloads are resolved when the partially applied function
is called
// with the remaining arguments.
struct S
{
static char fun(int i, string s)
{
return s[i];
}
static int fun(int a, int b)
{
return a * b;
}
}
void main()
{
alias fun3 = partial!(S.fun, 3);
writeln(fun3("hello")); // 'l'
writeln(fun3(10)); // 30
}
```
Hello Rikki,
thank you, this helps a lot although the polymorphism does not
work in my environment.
```
partial2.d:23:17: error: function std.functional.partial!(fun,
3).partial (string _param_0) is not callable using argument types
(int)
writeln(fun3(10)); // 30
```
But when I rename the functions for each case currying works well.
