I tried removing the depth tracking, but it causes test failures.
ParseAssignmentExpression() stops at ":" even when delimiters are unbalanced
(e.g.,num_teams((x+1:10) with missing )). Without depth tracking, this gets
misparsed as colon syntax instead of reporting the delimiter mismatch error.
My intention of using depth tracking to distinguish valid colon syntax from
malformed expressions.
Is there a better way to detect well-formed colon syntax that I'm missing?
