Not sure if this is a bug, or just some missing functionality of pure.

void f() pure {
  enum a = to!string("a"); // some legal compile-time to!()
}

Gives "to is not pure"

The following works:

template S(alias v) {
  enum S = to!string(v);
}
void g() pure {
  enum a = S!"a";
}

Should purity be checked at all if used with an enum?

Tested on dmd 2.057 / linux x64

I don't think so.

Thanks. Fixed in 2.059 perhaps? A long wait :)

I wouldn't hold my breath.
