Related to this: the current stumbling block for "quantitizer" is that
Quantities do not work with comparisons to Inf or -Inf. I will try to add
support for this as I think it is pretty unambiguous. I will also try to
support comparisons to 0 when the offset is 0 or None as this is also
unambiguous. What do you think?
