Predicate list_confusable_identifiers/1

 list_confusable_identifiers(+Options) is det
Walk every clause in the modules selected by module_class (default [user]) and warn on atoms whose written form is a possible UTS #39 spoof. Two issues are reported:
  • an atom whose unicode_restriction_level/2 is not safe (worse than single_script), reported at the first source location where it occurs;
  • groups of distinct atoms with equal unicode_skeleton/2 — two identifiers in the same program that look the same.

    Only atoms whose written form does not require quotes are considered (see '$needs_quotes'/1). Loaded via the multifile check:checker/2 hook, so a plain check/0 runs this check too.
