Bug 21457 – std.functional.partial ignores function overloads

As of DMD 2.094.0, the following program fails to compile: --- import std.functional; void fun(int x, string s) {} void fun(int x, int y) {} alias pfun = partial!(fun, 0); void main() { pfun("hello"); // ok pfun(123); // error } --- The compiler's output is: --- bug.d(11): Error: function std.functional.partial!(fun, 0).partial(string _param_0) is not callable using argument types (int) bug.d(11): cannot pass argument 123 of type int to parameter string _param_0 --- The cause is that partial!(fun, 0)(123) is attempting to call the first overload of `fun`, when it should instead be calling the second overload.

From source code: "// Assume fun is callable and uniquely defined." So either this should be documented or the template be improved...
