Revision history for Sub-Exporter

0.975   2007-07-04
        update Tutorial to show (preferred) \'name' style for generators
        changed "standard" name of curry_class to curry_method
        added curry_chain
        added Sub::Exporter::Cookbook

0.974   2007-04-22
        fix a bug that didn't mind trying to export a routine that didn't exist
        in the exporting package; this caused Sub::Install to give the
        unhelpful message "argument 'code' is not optional"

0.973   2007-02-02
        document changes made in 0.972
        minor code changes for readability

0.972   2006-12-05
        allow exporter config to provide name (via string ref) of generator for
        groups and exports
        similarly allow a string ref for a method name for a collector hook
        remove some pointless conditions

0.971   2006-11-06
        minor documentation clarification
        add Perl::Critic tests (disabled by default)

0.970   2006-06-27
        defaults populate before collectors collect, now
        default group's value is undef by default, not 1
        mixin_exporter can now export into objects, creating virtual classes
        
0.966   2006-06-17
        correct documentation of collector hook args
        simplify internal use of setup_exporter
        clean up documentation in ::Util

0.965   2006-06-05
        curry_class now allows the export to curry a differently-named method

0.961   2006-06-05
        Data::OptList is now in its own dist; updated to use it

0.960   2006-05-31
        added into and into_config to config
        100% test coverage... almost!
        fix bug that prevented validation of opt lists with must_be=class

0.954   2006-05-11
        tweaks to Data::OptList, moving toward its own dist: now it exports
        expand_opt_list is now opt_list_as_hash

0.953   2006-05-10
        require Params::Util for craftier opt list validation
        use reinstall, rather than install, to avoid warnings on redef

0.952   2006-04-30
        add missing file to manifest

0.951   2006-04-30
        fix util-mixin.t to skip if prereqs are missing
        various changes to improve blessed/weird generators
        (thanks to Yuval Kogman for pointing problems out)

0.95    2006-04-26
        break out Data::OptList for future disting
        remove an "optimization" that broke expand_opt_list
        improve detection of group generators
        improve data passed to hooks (if you relied on the guts, you'll break)
        the ::Util module

0.93    2006-03-26
        internal refactoring
        add more arguments to collector hook calls

0.92    2006-03-16
        FIX BUG in nested imports: when importing groups A and B, and group B
        includes group A, the nested group would be ignored, even though it was
        not recursing

        allow 'into_level' parameter to setup_exporter
        rewrite collection collector to be more efficient
        rewrite opt list handlers to be more efficient
        restate some code to improve clarity and coverage (now 100%)
        better diagnostic messages

0.91    2006-03-16
        added "import elsewhere" option to generated exporter (thanks chansen!)
