The term "free variable" has unfortunately become genuinely ambiguous over the years (presumably due to the names of some relevant code object instance attributes). While we can't eliminate that ambiguity at this late date, we can at least alert people to the potential ambiguity by describing both the formal meaning of the term and the common alternative use as a direct synonym for "closure variable". --------- (cherry picked from commit 2739099) Co-authored-by: Alyssa Coghlan <[email protected]> Co-authored-by: Carol Willing <[email protected]>
