NAME

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

VERSION

version 0.001013

SYNOPSIS

 package Syntax::Keyword::Gather;

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