+1 for this and for the other three hunks like it.  The resulting code is
shorter and more robust, so this is a good one-time cleanup.  It's not
important to mandate this style going forward, so I wouldn't change
perlcriticrc for this one.

This and the other "use warnings" additions look good.  I'm assuming you'd
change perlcriticrc like this:

+[TestingAndDebugging::RequireUseWarnings]
+severity = 5
