Hello,
what do you think about the idea of replacing "`else`" with "`then`" in
the contexts of `for` and `try`?
It seems clear that it should be rather "then" than "else." Compare also
"try ... then ... finally" with "try ... else ... finally".
Currently, with "else", it is almost impossible to guess the meaning
without looking into the documentation.
Off course, it should not be changed in Python 3, maybe in Python 4 or 5,
but in Python 3 `then` could be an alias of `else` in these contexts.
Alexey.
Apart from the questions of backward compatibility etc (Python is unlikely
to ever go through another shift like the 2/3 breakage), are you sure "then"
is what you mean? This won't print "end":
for i in range(10):
print(i)
else:
print(end)
Well, it'll bomb with NameError when it tries to look up the *name*
end. But it will run that line of code - if you quote it, it will
work.

Naturally, I messed up on both a shallow and deep level! :) Or should I
say derp level... :)
