I fear this idea is soon going to extend to all compound statements
one by one.
Wouldn't it be smarter to fix the issue once and for all by looking
into making Python's compound statements (or even all statements
without restrictions) expressions that can return values in the first
place? Now I don't know if it's actually possible, but if it is the
problem becomes solved not just for try:except: (and twice so for
if:else:) but also for while:, for: (though that one's already served
pretty well by comprehensions) and with:.
