Primitive Boolean type?

[Michael Lazzaro]

While writing documentation: a trivial question on the boolean type, C<bit>:

my bit $light_switch;

Q: Can bits/bools be undefined?

Perl conventions would indicate yes. Does that mean that an array of bits:

my bit @bitfield;

takes up, at minimum, two bits per, um, bit?

Sorry if this question is as stupid as it looks. I'm just worried that maybe it isn't.
