Except it doesn't work with literals properly:
assert(isIdentical(x, float.init)); // fails
This is what I'm trying to test. It has to do with the fact that
float.init is a literal, and I think it's automatically converted to
This code works:
I'm going to file a bug on this, float is float should just work!
