Maybe the naming should be according to Algebra.Unit:
Algebra.Zero as module name, and `query`

as method name.

defltIsZero :: (Eq a, C a) => a -> BoolSource

Checks if a number is the zero element.
This test is not possible for all `C`

types,
since e.g. a function type does not belong to Eq.
isZero is possible for some types where (==zero) fails
because there is no unique zero.
Examples are
vector (the length of the zero vector is unknown),
physical values (the unit of a zero quantity is unknown),
residue class (the modulus is unknown).
