This has been discussed before, and we've felt that it wasn't worth
the additional code duplication.  I would not favor approaching this
with the mindset of lets-copy-and-paste-all-the-code.

However: it might be interesting to think about having just two
underlying implementations, one for 32-bit datums and one for 64-bits,
with the existing APIs becoming macros-with-casts wrappers around the
appropriate one of those.  That line of attack might lead to
physically less code not more.  The devil's in the details though.
