Casting is very different from to, and useless for your purposes. You

druntime mustn't depend on Phobos, and I don't see why it is necessary.
What kind of functionality do you want to provide that depends on
std.conv.to ?
Casting from char[] to string is not what you want, and .idup is
specific to arrays. There must be one coherent method of "truely"
converting across types, and std.conv.to is the closest I can think of.

This will statically allow looking up an int in a T[string].
No, because of the other rules.

I see. An alternative solution (one that does not make AAs depend on
Phobos and is more slick) would be to use the const qualified key type
for lookup (that is what const is for) and to have immutable keys for
stores. For types that define .idup, there would be another overload of
opIndexAssign that can take a const qualified key.
