[prog] Member variables in Perl

[Dan Richter]

Hi everyone.

Perl has the peculiarity of implementing each object as a hash, with its 
member variable names as keys and the values as values. (Sure, you don't 
HAVE to do it that way - There Is More Than One Way To Do It [TIMTOWDY] - 
but in most cases it's the only sane way.)

This introduces the possibility of collisions between parent class and 
subclass data. Are there any generally accepted ways of avoiding such 
collisions?
