NAME¶
Modern::Perl - enable all of the features of Modern Perl with one import
VERSION¶
version 1.20140107
SYNOPSIS¶
Modern Perl programs use several modules to enable additional features of Perl
and of the CPAN. Instead of copying and pasting all of these "use"
lines, instead write only one:
use Modern::Perl;
This enables the strict and warnings pragmas, as well as all of the features
available in Perl 5.10. It also enables C3 method resolution order as
documented in "perldoc mro" and loads IO::File and IO::Handle so
that you may call methods on filehandles. In the future, it may include
additional core modules and pragmas.
Because so much of this module's behavior uses lexically scoped pragmas, you may
disable these pragmas within an inner scope with:
no Modern::Perl;

Forward Compatibility¶
For forward compatibility, I recommend you specify a
year as the single
optional import tag. For example:
use Modern::Perl '2009';
use Modern::Perl '2010';
... both enable 5.10 features, while:
use Modern::Perl '2011';
... enables 5.12 features:
use Modern::Perl '2012';
... enables 5.14 features:
use Modern::Perl '2013';
... enables 5.16 features, and:
use Modern::Perl '2014';
... enables 5.18 features. Obviously you cannot use newer features on earlier
versions. Perl will throw the appropriate exception if you try.
By mid-2014, this module will drop support for 5.10 and 5.12 and will complain
(once per process) if you use a year too old. As of January 2014, Perl 5.14 is
unsupported by the Perl 5 Porters, so please consider upgrading.
