Josh Rosenberg added the comment:
Does this introduce a slowdown when the type doesn't match? That is, clearly
George's example:
try:
{}["a"]
except KeyError:
pass
won't be slowed because the fast path will get an immediate hit. But what about:
try:
{}["a"]
except TypeError:
pass
except ValueError:
pass
except KeyError:
pass
(or with the KeyError handler higher up the call stack). The fast path speeds
up the handled case, but it doesn't seem like it would help the unhandled case
(where it would need to check the slow path for each unhandled exception type
one at a time).
