I'll have to implement a similar module for WDDX. I can't use copy_reg
because WDDX has a cross-language requirement. I can't encode the type
name in terms of modules and constructor functions: I must indirect
through a URI.

I can make a two-way registry which describes mappings both way. Then I'll
prime the registry with any date/time classes people give me URLs for.
Then users can choose their own date/time class. Whichever one appears as
input (mxDateTime, /F's, etc.) will get interpreted correctly as a date.
