I try to keep it simple, as possible - so I hope the performance is well, but it will not work in each case thatswhy. But it has some features I can easy realize with this code. A real live example would be a modul which has for each HTML Tag from Tagset a subroutine. There are to much possible combinations to build a tag for each. Exporting all makes things slower if it is imported from many places. Ensure somewhere is the namespace "from" loaded.

package A;

import from 'HTML::TAGS::AsFunctions' => 'Div A Img';

Another usecase is to export subroutines.

package B;

sub import{
   export from _ => qw/foo bar/
}

And the third, it enables you to relay subroutines.

package SubRelay;

sub import{
   export from FooModule => 'foo';
   export from BarPackage => 'bar';
}
