only input data is modified

module main;
import std.stdio;
import std.process;

void Function(in uint[int]o_a){
  foreach(l_a; o_a.keys)o_a.remove(l_a);
}

void
main(char [][] args){
  uint[int]l_a;
  l_a[1] = 0;
  l_a[2] = 3;
  writefln(l_a.length);  // 2
  Function(l_a);
  writefln(l_a.length);  // 0
  system("pause");
}

That act's as I would expect. (AA's are reference objects) If you want to not effect the AA on the outside then set it to null (better check that) on the inside function. If you want to remove only some things and only do /that/ on the inside, your sunk.
