By requiring explicitly a minimal Perl version number for your program, with
the C<use VERSION> construct, and when the version is higher than or equal to
-5.9.5. That is,
+5.10.0. That is,
- use 5.9.5;
+ use 5.10.0;
will do an implicit
- use feature ':5.9.5';
+ use feature ':5.10.0';
and so on.
+But to avoid portability warnings (see L<perlfunc/use>), you may prefer:
+
+ use 5.010;
+
+with the same effect.
