Give @sasajuric 's method a try.

Shared module constants

I would definitely go for the approach from @michalmuskala. One problem with maps is that it only supports one way conversion (converting a const into an integer). If you need to convert an integer into a const, you’ll have to build a reversal map. This can be easily done, even during compilation time, but then the code becomes as complex if not more than Michal’s version. Moreover, I’m not completely sure whether this map is stored in the so called “constant pool”, and if it’s not, then the p…

IMO, it’s simple and powerful.
