It's really only used to handle equality checks all together, but just putting individual types in a contiguous range and doing a range comparison will work as well.

This changes a == b == c == d from having constant stack/parse tree depth to linear depth.  Unless someone has evidence that this pattern gets real use (remember the left stuff decays, so you every term compared to true/false from the left hand side), this seems like more intuitive, more intelligent behavior to me.
