Re^2: Which pragmas are activated with a specific perl version?

And taking the information from "Feature Bundles":

# no "use VERSION" is the same as:
use feature qw/array_base/;

use 5.010;  # is the same as:
use feature qw/say state switch array_base/;

use 5.012;  # is the same as:
use strict;
use feature qw/say state switch unicode_strings array_base/;

use 5.014;  # is the same as:
use strict;
use feature qw/say state switch unicode_strings array_base/;

use 5.016;  # is the same as:
use strict;
use feature qw/say state switch unicode_strings
               unicode_eval evalbytes current_sub fc/;

use 5.018;  # is the same as:
use strict;
use feature qw/say state switch unicode_strings
               unicode_eval evalbytes current_sub fc/;

use 5.020;  # is the same as:
use strict;
use feature qw/say state switch unicode_strings
               unicode_eval evalbytes current_sub fc/;

use 5.022;  # is the same as:
use strict;
use feature qw/say state switch unicode_strings
               unicode_eval evalbytes current_sub fc/;

use 5.024;  # is the same as:
use strict;
use feature qw/say state switch unicode_strings
               unicode_eval evalbytes current_sub fc
               postderef_qq/;

use 5.026;  # is the same as:
use strict;
use feature qw/say state switch unicode_strings
               unicode_eval evalbytes current_sub fc
               postderef_qq/;

Thanks! This answers my question. But I have a new one :-) Where did you get this version of the table? My `perldoc` and the web based documentation have a different table: `The following feature bundles are available: bundle features included --------- ----------------- :default array_base :5.10 say state switch array_base :5.12 say state switch unicode_strings array_base :5.14 say state switch unicode_strings array_base :5.16 say state switch unicode_strings unicode_eval evalbytes current_sub fc :5.18 say state switch unicode_strings unicode_eval evalbytes current_sub fc ...` [download]	[reply] [d/l] [select]

Where did you get this version of the table? I got it from the link I posted (http://perldoc.perl.org/feature.html#FEATURE-BUNDLES), which at the moment is the Perl 5.26.1 documentation. The table you showed has the same entries - I assume you have Perl 5.18 installed, which is why your table doesn't go any further. If you want to stay absolutely up-to-date, see the `%feature_bundle` hash (and the corresponding table near the bottom of the file) in lib/feature.pm in the Perl source repository (Update: or regen/feature.pl). According to that, the features for `use 5.028;` will be `qw/say state switch unicode_strings unicode_eval evalbytes current_sub fc postderef_qq bitwise/` (subject to change, of course).
