New Issue: Random: adaptor for the implementation core

19605, "vasslitvinov", "Random: adaptor for the implementation core", "2022-04-05T20:10:34Z"

Can we implement the core functionality of PCGRandomStream in a way that is independent of eltType?

This way we can reduce the amount of code duplication that results from instantiating PCGRandomStream for each eltType.

eltType-specific functionality would come from an adaptor/wrapper.
