Currently it is impossible to have the compiler figure out which overloaded function
to call when they are defined in different modules unless you specify a module path,
even with aliases. ie, this code wont work: (the modules are in different files)

<code>
module foomod;
struct Foo {
	char[] name;
	int value;
}

char[] toString(Foo foo) {
	return name;
}

module main;
import foomod, std.string;

uint i;
Foo f;

main() {
	writefln(toString(f)); // fails if "alias std.string.toString toString" is defined last
	writefln(toString(i));  // fails if "alias Foo.toString toString" is defined last
	// Both fail if neither are defined
}

</code>

Now I know I could alias them as different symbols, but then you lose the whole point of overloading.

You need to have two alias declarations. The following works:

---------------- foomod.d ---------------------
module foomod;

struct Foo {
char[] name;
int value;
}

char[] toString(Foo foo) {
return foo.name;
}

----------------- test.d --------------------------
module main;
import foomod, std.string, std.stdio;

alias std.string.toString toString;
alias foomod.toString toString;

uint i;
Foo f;

void main() {
writefln(toString(f));
writefln(toString(i));
}

-----------------------------------------------------

huh... I swore I tried that... Whoops. (You didnt change any import stuff from 1.02, did you?)
