Decide to throw the question away and name the thing Package Subs. Looks intuitive too and now it fits the recommended practices. <cite> Is the name well chosen? I wrote this lightweight Exporter alternative and want to start this tiny thing on CPAN. But it is maybe critizised to much there or it's not worth to stay there. So it is safer to ask here before. </cite>

Some hints applied, so the examples using a string are broken. :) Thank you all to finding this out. :)
