Also, I like it for testing, when I want to test .kind_of? and ensure
that it’s either true or false.
It’s been proposed and rejected by Matz once already.
i seem to recall this… link? wonder why he rejected…
I think one of the reasons for rejecting it was that redefining how true
or false behaved would cause havoc with the regular expression engine.
But I think mostly he just didn’t see the need for a boolean class the
ways things are now.
