Sure would, if someone's expecting a key to have
a normal numeric value.  I won't try to pursue
the point further, I'm just trying to leave you 
with an idea of how crappy a workaround would look.

Doesn't work (the bottom line is that string assignment doesn't 
copy SvMAGIC, but I won't bore you with the sv_setsv details).

Anyways, I still think it's best to just document the 
brokenness of the TIEHASH API for APR::Tables, since

  1) perl's TIEHASH API is stupendously slow anyways,
  2) it isn't designed to handle multivalued keys.
