That's not an improvement. The above code fragment should trigger a gag
reflex indicating that something is wrong with the proposed default for
a bare except.

The data gathered by Jack and Steven's research indicate that the number
of cases where TerminatingException would be useful is ZERO. Try not to
introduce a new builtin that no one will ever use. Try not to add a new
word whose only function is to replace a two-word tuple (TOOWTDI). Try
not to unnecessarily nest the tree (FITBN). Try not to propose
solutions to problems that don't exist (PBP).
