values; that makes sense.
Good! Thanks.

example, I don't think that reduction for a degenerate form makes sense,
and there are cases where we don't have an implementation for for a
specific class of forms (indefinite, say). Thoughts?
OK by me to restrict to B which are 0 or 1 mod 4 and not squares.
