I want to ask what you think about introducing a keyword 'eltry' which would be the counterpart of 'elif' for try statements. This had been suggested before on python-list a couple of years ago by Jonathan Gardner, but nothing (that I could find) seems to have come of it.

I'm -1 on this. The use case doesn't occur often in my experience and IMO putting each try statement in the else clause of the previous one is a fine solution.

I also notice that your only example is very repetitive, and would be better written as a loop, using Python's dynamic nature:

for decoder in foo_decode, bar_decode, foobar_decode: try: data = decoder(data) break except ValueError: print "data doesn't seem to be %s-encoded" % decoder.name
