Would it not be possible to still keep the math parts in (internal)
non-templated functions?  It feels like the duplication should mostly
be in the interface parts.

For instance, a single addition function could take 2 ranges of
pointers and perform all the addition logic independently of the
template parameters.  Then the various templates would arrange the
storage properly, call the function, and translate any errors
appropriately (not that there'd be any errors for addition, though I
suppose there might be a carry).
