keep in mind that there is still this %^H hint-hash mechanism for lexically scoped exports.

See perlpragma , though the routines are not really unimported they are just aware about the correct scope.

There are so many paths, so much OWTDI, and to get a good one, so many things want to be thinked about... Thanks. perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'	[reply]
