(exc, val, tb) triplet to one value (original) (raw)

@markshannon suggested to change the (exc, val, tb) triplets on the interpreter that represent exceptions into one: if it's a normalized exception, just the exception itself. If it isn't, make it a 3-tuple of the values.

The advantage is that 3 POPS and pushes become one, and the code is simplified in various places.
