Would you also go as far as to say that you'd expect the 
following to be perfectly valid D code?

---------
module a;

void foo(T : int)() { }

---------
module b;

void foo(T : string)() { }

---------
module main;

import std.stdio;

import a;
import b;

alias foo = a.foo;
alias foo = b.foo; // [1]

void main()
{
     foo!int();
     foo!string();
}

---------
1) Error: alias main.foo conflicts with alias main.foo
