It depends entirely what Perls you want to support. If you only want to support Perl 5.10 or newer, module versions in the dotted-decimal form are fine as long as you always declare them as strings and don't use underscores. If you want to support older than that, you have to jump through some hoops or risk users getting the wrong behavior.
For the 'use X' statement itself for declaring a minimum perl version of a file, the '5.XXXYYY' format is still (always?) recommended, because it will make sure that running it on older Perls will result in a sensible error message. -Dan On Tue, Apr 16, 2019 at 3:54 PM John M.
