   I am with  Jim on this part (but only on this). I'd like this

class Test:
    def __str__(self):
        return "STR"

    def __repr__(self):
        return "REPR"

test = Test()
print test
print repr(test)
print str(test)
print [test]
print str([test])
print repr([test])

   to print

STR
REPR
STR
[STR]
[STR]
[REPR]

   but the code actually prints

STR
REPR
STR
[REPR]
[REPR]
[REPR]

   str(container) not calling str() on items is at least a strange and
unexpected behaviour, if not a bug.
   Unfortunately, it is not easy to fix, and missing quotes on string items
is a loose (albeit a minor one for me), so I accepted the compromise - to
fix repr() and forget about str(container).

Oleg.

           Programmers don't die, they just GOSUB without RETURN.
