Hopefully that is clear.

Jonathan M Davis:
But I certainly agree that it would be nice if there were a
function that
inserted the element if it wasn't already there and then

UFCS would do it:
import std.traits;
auto ref set(Hash, Key, Val)(Hash hash, Key key, Val val)
if (isAssociativeArray!Hash &&
is(Key : KeyType!Hash) &&
is(Val : ValueType!Hash))

it.
