This is good stuff to know, but in practice it is generally better to avoid excessive global variables, and packages which do use global variables should use Exporter to decide which ones to export.

Poking around in someone else's namespace is quite doable, but I consider it sort of like walking into someone else's house uninvited and browsing around. Rather rude, wouldn't you say?
