My use case is fairly simple: I have a constrained, contiguous integer
range and a second set of integers of the same size that are constrained
but not contiguous. The latter set is a unique "geographical"
descriptor for an element of a particle detector, where the integer
carries human readable location information. The former is a
corresponding "serial number" in a contiguous range (useful for making
plots and addressing arrays). Some operations are efficient in one of
these spaces and not the other, and since I will have many terabytes of
data at the end of the day, it would be nice if operations were as
efficient as bare integers, and conversions between these types need to
be fast. Operations should be transparently integer like to the extent

Not at all at this time
