So, the improvement is that before prepareForUnit returned all the symbols for getClass methods, by generating stubsymbols were needed, and now it doesn't?

Yes. Mostly the cost was in creating the set.

I think you could just do defn.ScalaValueClasses.contains, no need for the intermediate variable.

There is some performance regression on some of the exhaustivity benchmarks. I will investigate before merging. |
