NAME

Sub::Exporter::Progressive - Only use Sub::Exporter if you need it

SYNOPSIS

package Syntax::Keyword::Gather;

use Sub::Exporter::Progressive -setup => {
  exports => [qw( break gather gathered take )],
  groups => {
    defaults => [qw( break gather gathered take )],
  },
};

# elsewhere

# uses Exporter for speed
use Syntax::Keyword::Gather;

# somewhere else

# uses Sub::Exporter for features
use Syntax::Keyword::Gather 'gather', take => { -as => 'grab' };

DESCRIPTION

Sub::Exporter is an incredibly powerful module, but with that power comes great responsibility, er- as well as some runtime penalties. This module is a Sub::Exporter wrapper that will let your users just use Exporter if all they are doing is picking exports, but use Sub::Exporter if your users try to use Sub::Exporter's more advanced features features, like renaming exports, if they try to use them.

Note that this module will export @EXPORT, @EXPORT_OK and %EXPORT_TAGS package variables for Exporter to work. Additionally, if your package uses advanced Sub::Exporter features like currying, this module will only ever use Sub::Exporter, so you might as well use it directly.
