Comment:
OK, here is an implementation for this.
The object returned from the `variety()` call no longer is a sequence,
since converting to sequence will cause some argument misalignment and
therefore make all solutions come up as empty dicts. One alternative would
be making the key conversion function a named argument, perhaps even
guessing it from the type of the keys provided so far. Another alternative
would be introducing a category for conversion dicts, one for every
possible conversion function. But I doubt either of these is neccessary,
since I doubt anyone really relies on receiving a Sequence out of this.
Should `BooleanPolynomialIdeal.variety()` in `pbori.pyx` behave the same?
Should other code make use of this as well, e.g. the symbolic `solve`
function with `solutions_dict=True`? Should these things be handled in
separate tickets?
