Some use L, some use L, some use L, some use L ... and some things are pragmas. If you want to re-export other things, you have to know which is which. L subclasses provide export_to_level, but if they overrode their import method all bets are off. L provides an into parameter but figuring out something used it isn't trivial. Pragmas need to have their C method called directly since they affect the current unit of compilation. It's ... annoying. However, there is an approach that actually works for all of these types. eval "package $target; use $thing;" will work for anything checking caller, which is everything except pragmas. But it doesn't work for pragmas - pragmas need: $thing->import; So, the solution is: my $sub = eval "package $target; sub { shift->import(\@_) }"; $sub->($thing, @import_args); which means that import is called from the right place for pragmas to take effect, and from the right package for caller checking to work. Remembering all this, however, is excessively irritating. So I wrote a module so I didn't have to anymore. Loading L will create a method C which you can call on a package to import it into another package. So now you can simply write: use Import::Into; $thing->import::into($target, @import_args); Just make sure you already loaded C<$thing> - if you're receiving this from a parameter, I recommend using L: use Import::Into; use Module::Runtime qw(use_module); use_module($thing)->import::into($target, @import_args); And that's it. =head1 AUTHOR mst - Matt S.
