Exporting "everything" probably isn't right, but I've been known to do this (for production code, in fact):

use vars qw(@EXPORT);
...
sub foo {
  ...
}
push @EXPORT, 'foo';
...
sub bar {
  ...
}
push @EXPORT, 'bar';
...

and so on. Then when I'm adding or deleting a subroutine, the code to "export" it is right there.
