My commit 3d49ad73e5 from 2021-09-143 had a flaw causing bad
fontification and indentation after anonymous subroutines with
a prototype.
* lisp/progmodes/cperl-mode.el (cperl-find-pods-heres): Correctly
process prototypes in anonymous subroutines
* test/lisp/progmodes/cperl-mode-tests.el
(cperl-test-fontify-attrs-and-signatures): new tests for various
combinations of attributes, prototypes, and signatures
* test/lisp/progmodes/cperl-mode-resources/proto-and-attrs.pl: new
