# Bootstrap Scheme V0.2 (Booleans) In Ada

Booleans were very trivial to add after laying down the foundation with
v0.1. The only real difference between booleans and integers, as Peter notes, is
that `#t`

and `#f`

are singletons and only one instance of
each is ever created. With integers, a new object is created everytime we need
one. What took the longest this time around was fixing the bugs that I
discovered in v0.1 where spaces weren't being properly ignored and negative
numbers would throw exceptions. Apparently, I'm a sloppy coder. All fixed now
though, and the new v0.2
branch is on GitHub.
