Re: TrueClass/FalseClass vs. Boolean

Ruby

when Boolean

would undoubtably lead to some nice logical constructs that
more closely parallel the way we think.

Think ‘NULL’ in databases, where ‘NULL’ is may not mean true or false,
but unknown. At the moment, NULL maps to nil, which is false.

i’ve brought this up once or twice before - maybe we should
just put together a patch and send to ruby-core?

It’s been proposed and rejected by Matz once already.
