. If an object constructor exit()s, the object destructor will no longer be
201201
called. This matches the behavior when the constructor throws.
202+
. Non-strict comparisons between numbers and non-numeric strings now work by
203+
casting the number to string and comparing the strings. Comparisons between
204+
numbers and numeric strings continue to work as before. Notably, this means
205+
that `0 == "not-a-number"` is considered false now.
