What
Fix comparison in
Tag::is_object
.Why
This function incorrectly always returns true. The more-commonly-used
Val::is_object
is correct. This patch makes both functions agree.I would prefer
Val::is_object
delegate toTag::is_object
, but that can't be done without constructing aTag
, which has several branches, and I take itVal::is_object
is a fast path.Known limitations
Tag::is_object
andVal::is_object
duplicate code.
