My guess is that this issue will be resolved by allowing users to add
overloads within namespace std.  I don't like that solution; I think it's
drastic.  However, I also don't like any of the other solutions that have
been proposed.  My impression of Core's position is that they are reluctant
to make major core language changes like adding support for partial 
specialization of functions.

It's probably worth restarting the discussion about this, and seeing if 
anyone has new ideas.
