Why does not indenting the case tags break a fundamental property of
indentation? Why is something like (using syntax suggested in PEP
275):

when my_value:
    # Can we do something useful with this?
in (...):
    code
in (...):
    more code
else:
    yet more code

Any worse than:

if my_value in (...): code
elif my_value in (...):
    more code
else:
    more code


I don't see a real problem with the first case.

And yes, I like the when ... in syntax suggestion.
