do you think? Separate ticket, or fix here?
This routine is an extension of the idea of a dot product. So I'd say the
dot product is broken and needs to be more careful about mixing the two
base rings. Maybe it should check compatibility, and if there is no
conflict, then go on its way. If there is a conflict, the vectors should
be converted to a common base ring, then do the dot product. If that does
not work, then the routine should fail gracefully.
So I'd like that to be on another ticket. If you make the ticket and cc
me, then I'll put it on my list for SD 29 next week, and coordinate with
this ticket, if necessary. But I'd like to see this go in pretty much as-
is and let improvements to the "plain" dot product improve this routine
from outside.
Thanks,
Rob
