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__
