NAME

namespace::lexical - like namespace::clean but instead of deleting subs, makes them lexical

SYNOPSIS

package My::Class;
use Scalar::Util 'blessed';
use namespace::lexical;

# blessed() is available here but there
# is no My::Class->blessed() method.

package My::Other::Class;

# blessed() is still available here!!!

DESCRIPTION

namespace::lexical works a lot like namespace::clean but rather than removing functions from your namespace, it converts them into lexical subs (like my sub foo { ... } on Perl 5.18 and above).

namespace::lexical requires Perl 5.12 or above.

API

import

The standard way to use this module is:

use namespace::lexical;

This will loop through all functions defined so far in the caller package and lexicalize them.

lexicalize($stash, $subname, $coderef)

This method should be passed a Package::Stash object, a sub name, and an optional coderef. It will remove the sub by name from the provided stash, and install the coderef into the caller lexical scope using the given name.

If no coderef is given, it will grab the existing coderef from the stash.

If the stash is undef, it will skip removing the sub from the stash and only install the lexical version.

The coderef and stash cannot both be undef.

Most end users will have no reason to call this method directly.
