Rationale (http://digitalmars.com/d/2.0/rationale.html) says:"""Why not use operator names like __add__ and __div__ instead of opAdd, opDiv, etc.?
__ keywords should indicate a proprietary language extension, not a basic part of the language. """
But traits is explained under the language spec, http://digitalmars.com/d/2.0/traits.html.
Can I expect traits to exist for all compiler implementations, or just dmd?
