Hi @fhahn, I think this is pretty confusing. Can we rename the existing `getNumUsers` to `getNumUses` to more closely match the naming conventions using for IR values? If a recipe has duplicate input operands then the number of uses != 1, but the number of users may still be 1. If so, I'd like to put up a patch to tidy this up a little.
