Probably never.

Like most programming languages Python has a load of rarely used,
obscure features. Most Python programmers never use ellipses,
metaclasses(*), the __new__() constructor, the _ variable or
even the else clause in a loop. That doesn't mean you shouldn't
look into them - they might just be the bit of magic you
need - but don't feel you need to have a use for every
bit of the language.

(*) Actually, everyone uses metaclasses, but very few define
their own!
