Peter,
This isn't a ram consideration as much it's a logical consideration. There are
a lot of ways to handle this, I REALLY don't want to use a package here. Bit
masking is incredibly useful for permutations/combinatoric algorithms. I can
create my own class wrapper or functions, and optimize,

@MRAB,
Yes -- good point, it should be the __and__ operator.
do I need a new class? No, but based on this use case and other formatting
techniques adding a filter method to the list class that takes in either bit
mask or bool list would streamline a lot of code and not change any existing
func

I frequently use binary as bool placeholders and find myself filtering lists
based on those bools, this seems to have a similar semantic meaning as the bit
wise ^ or __xor__ operator and could add syntactic sugar to the base list class.
