I've had to debug code that assumed str(reversed('abc')) == 'cba'
>>> str(reversed('abc'))
'<reversed object at 0xa66f78c>'
So, a str doesn't "construct" like tuple/list...it's a call to
__str__().
It's designated as a "friendly print out" (that's my phrasing).
>>> list('abc')
['a', 'b', 'c']
I s'pose str is special (2.6) in some way, but it doesn't parallel the
other builtins.
