| Summary : Experimental features made easy
|
Description :
This pragma provides an easy and convenient way to enable or disable
experimental features.
Every version of perl has some number of features present but considered
\"experimental.\" For much of the life of Perl 5, this was only a designation
found in the documentation. Starting in Perl v5.10.0, and more aggressively
in v5.18.0, experimental features were placed behind pragmata used to
enable the feature and disable associated warnings.
The \'experimental\' pragma exists to combine the required incantations into
a single interface stable across releases of perl. For every experimental
feature, this should enable the feature and silence warnings for the
enclosing lexical scope:
use experimental \'feature-name\';
To disable the feature and, if applicable, re-enable any warnings, use:
no experimental \'feature-name\';
The supported features, documented further below, are:
* * \'args_array_with_signatures\' - allow \'AATT_\' to be used in signatured
subs.
This is supported on perl 5.20.0 and above, but is likely to be removed in
the future.
* * \'array_base\' - allow the use of \'$[\' to change the starting index of
\'AATTarray\'.
This was removed in perl 5.30.0.
* * \'autoderef\' - allow push, each, keys, and other built-ins on
references.
This was added in perl 5.14.0 and removed in perl 5.24.0.
* * \'bitwise\' - allow the new stringwise bit operators
This was added in perl 5.22.0.
* * \'builtin\' - allow the use of the functions in the builtin:: namespace
This was added in perl 5.36.0
* * \'const_attr\' - allow the :const attribute on subs
This was added in perl 5.22.0.
* * \'declared_refs\' - enables aliasing via assignment to references
This was added in perl 5.26.0.
* * \'defer\' - enables the use of defer blocks
This was added in perl 5.36.0
* * \'extra_paired_delimiters\' - enables the use of more paired string
delimiters than the
traditional four, \'< >>>>, \'( )\', \'{ }\', and \'[ ]\'.\'
This was added in perl 5.36.
* * \'for_list\' - allows iterating over multiple values at a time with \'for\'
This was added in perl 5.36.0
* * \'isa\' - allow the use of the \'isa\' infix operator
This was added in perl 5.32.0.
* * \'lexical_topic\' - allow the use of lexical \'$_\' via \'my $_\'.
This was added in perl 5.10.0 and removed in perl 5.24.0.
* * \'lexical_subs\' - allow the use of lexical subroutines.
This was added in 5.18.0, and became non-experimental (and always enabled)
in 5.26.0.
* * \'postderef\' - allow the use of postfix dereferencing expressions
This was added in perl 5.20.0, and became non-experimental (and always
enabled) in 5.24.0.
* * \'postderef_qq\' - allow the use of postfix dereferencing expressions
inside interpolating strings
This was added in perl 5.20.0, and became non-experimental (and always
enabled) in 5.24.0.
* * \'re_strict\' - enables strict mode in regular expressions
This was added in perl 5.22.0.
* * \'refaliasing\' - allow aliasing via \'\\$x = \\$y\'
This was added in perl 5.22.0.
* * \'regex_sets\' - allow extended bracketed character classes in regexps
This was added in perl 5.18.0.
* * \'signatures\' - allow subroutine signatures (for named arguments)
This was added in perl 5.20.0.
* * \'smartmatch\' - allow the use of \'~~\'
This was added in perl 5.10.0, but it should be noted there are significant
incompatibilities between 5.10.0 and 5.10.1.
The feature is going to be deprecated in perl 5.38.0, and removed in
5.42.0.
* * \'switch\' - allow the use of \'~~\', given, and when
This was added in perl 5.10.0.
The feature is going to be deprecated in perl 5.38.0, and removed in
5.42.0.
* * \'try\' - allow the use of \'try\' and \'catch\'
This was added in perl 5.34.0
* * \'win32_perlio\' - allows the use of the :win32 IO layer.
This was added on perl 5.22.0.
