Adds pragmata to Exporter

 Pragmatic implements a default import method for processing pragmata before
 passing the rest of the import to Exporter.
 .
 Perl automatically calls the import method when processing a use statement
 for a module. Modules and use are documented in perlfunc and perlmod.
 .
 (Do not confuse Pragmatic with pragmatic modules, such as less, strict and
 the like. They are standalone pragmata, and are not associated with any other
 module.)
