* lisp/progmodes/cperl-mode.el (cperl-init-faces): Reorder the
matchers for fontification of array and hash elements and keys so
that they don't override comment and string fontification (Bug#66145).
* test/lisp/progmodes/cperl-mode-tests.el (cperl-test-bug-66145):
New test for all combinations of sigils and brackets/braces to
verify that strings and comments are left untouched. This test
also works for perl-mode which has always done it correctly.
* test/lisp/progmodes/cperl-mode-resources/cperl-bug-66145.pl: New
resource file for the above test.
