Hi,

I'd like to write a new checker for pylint to cover the following cases of misused comprehensions (and recommended replacements):

[x for x in y] -> list(y)
any([x for x in y if z]) -> any(x for x in y if z)
all([x for x in y if z]) -> all(x for x in y if z)
[x for x in y if z][0] -> next(x for x in y if z)
set([x for x in y if z]) -> {x for x in y if z}

I'm wondering if (1) this functionality already exists somewhere (I couldn't find it), and (2) if not, would you be amenable to a PR that adds such a checker?

Thanks,

Nathan
