Description
sage.symbolic.units.is_unit
should be renamed, since there are is_unit
methods for Expression
and Integer
, for example, with completely different functionality. This is confusing, especially since you can do the following:
sage: units.length.meter.is_unit() True sage: x.is_unit() True sage: sage.symbolic.units.is_unit(units.length.meter) True sage: sage.symbolic.units.is_unit(x) False
Perhaps something like is_measurement_unit
would be better?

I believe (I haven't checked this) that those
is_unit()
methods are on instances ofExpression
andInteger
, not for direct use. Plus by explicitly callingsage.symbolic.units.is_unit()
, you should know what you're doing. However theis_*
functions are deprecated from the global namespace (not to mention that it seems like this is not even in the global namespace) and this might even be a simple enough function that it can be removed, see #12824.Thus I'm thinking this ticket should be closed, but a small patch to change the name might not hurt...
