for parallelism with if/else operator I'd like

    float('some text') except ValueError then 42

which is equivalent to calling:

    def f():
      try:
        return float('some text')
      except ValueError
        return 42

For example,

    float(foo) except ValueError then None if foo else 0

or equivalently:

     float(foo) if foo else 0 except ValueError then None

Of course this requires a new keyword so the chances of this being added are
slim.
