named constants in expressions?
I am interpreting a binary format that contains integers that have to be scaled by factors given by (mostly negative) powers of two, so 2^-43 (1.136868377216160e-13), 2^-31 (4.656612873077393e-10) etc. The feature of using scaled instances is really nice to allow this scaling, however, the constants are hard to read. It would be nice to be able to used named constants instead. Is this possible at all?
