Export Shared Globs with Sub::Exporter Collectors

Sub::Exporter::GlobExporter provides only one routine, 'glob_exporter', which may be called either by its full name or may be imported on request. my $exporter = glob_exporter( $default_name, $globref_locator ); The routine returns a collection validator|Sub::Exporter/Collector Configuration that will export a glob into the importing package. It will export it under the name '$default_name', unless an alternate name is given (as shown above). The glob that is installed is specified by the '$globref_locator', which can be either the globref itself, or a reference to a string which will be called on the exporter For an example, see the /SYNOPSIS, in which a method is defined to produce the globref to share. This allows the glob-exporting package to be subclassed, so the subclass may choose to either re-use the same glob when exporting or to export a new one. If there are entries in the arguments to the globref-exporting collector _other_ than those beginning with a dash, a hashref of them will be passed to the globref locator. In other words, if we were to write this: use Shared::Symbol '$Symbol' => { arg => 1, -as => 2 }; It would result in a call like the following: my $globref = Shared::Symbol->_shared_globref({ arg => 1 });
