I would assume that this would be a limit of strong typing; if you want to do 
stuff like determining your @ISA at runtime, or using 'require A; A->import'
you are welcome to do so but don't expect strong typing to be of any help.

Otherwise, I see very little point to it if no compile time checks are 
available.
