From use in http://perl5.git.perl.org/perl.git/blob_plain/HEAD:/pod/perl5114delta.pod:

Also, if the specified Perl version is greater than or equal to 5.9.5, "use VERSION" will also load the "feature" pragma and enable all features available in the requested version. See feature. Similarly, if the specified Perl version is greater than or equal to 5.11.0, strictures are enabled lexically as with "use strict" (except that the strict.pm file is not actually loaded).
