> Thanks for the feedback. I put these new functions in `Evaluate/tools.h` since `IsTeamType` and `IsEventTypeOrLockType` are both there. I don't have a strong feeling where they should go, but if I move the new functions, then I think those other functions should probably also be moved. What do you think?
Gee, `IsTeamType` is referenced in `Evaluate/intrinsics.cpp`, so it can't be moved even though it's logically related to the other functions.  But `IsEventTypeOrLockType` is only referenced from the `Semantics` directory.  For locality of reference, it make sense to me to move them.
