The most common use case I find for this is when dealing with JSON (as
someone else pointed out). But that's a definite case of dealing with
data in a format that's "unnatural" for Python (by definition, JSON is
"natural" for JavaScript). While having better support for working
with JSON would be nice, I typically find myself wishing for better
JSON handling libraries (ones that deal better with mappings with
known keys) than for language features. But of course, I could write
such a library myself, if it mattered sufficiently to me - and it
never seems *that* important :-)
