So, this is kind of like Perl's unless?

The main motivation is to provide syntactic alternative to proliferation
of default value options, so that
x = getattr(u, 'answer', 42)
can be written as
x = y.answer except ... 42
For a dictionary d,
x = d.get('answer', 42)
can be written as
x = d['answer'] except ... 42
For a list L,
try:
x = L[i]
except IndexError:
x= 42
can be written as
x = L[i] except ... 42
The ellipsis in the above stands for syntax being debated.
Effectively, Python is about to gain support for a new operator and
operators are very precious for numpy. So, I think numpy community has a
horse in that race.
