1.0.16

1.0.16 (2021-05-03)

Another small release with the following changes:

dcg

• Removal of many DCG rules that now can be implemented by using the more generic abnf module.
• Added error_location/[2,3] for communicating parsing errors to the user.

sort_ext

• Added order_by2/2 as an alternative to the built-in order_by/2 predicate. The difference that this order_by2/2 is able to handle
  the empty list of ordering commands (useful in situations where the ordered commands are generated algorithmically).

term_ext

• Added shared_vars/3 as a convenience predicate for shared_vars/2 that calculates the shared variables between exactly two terms.
