That's not right. for-statements are not touched.

Only contains expressions are translated:
"if x in [1,2,3]"
currently turns into:
"if x in (1,2,3)"
and I'm proposing that it go one step further:
"if x in Seachset([1,2,3])"
where Search set is a frozenset subtype that doesn't require x to be
hashable. Also, the transformation would only happen when the contents
of the search are all constants.
