Bootstrap Scheme V0.2 (Booleans) In Ada

January 13th, 2010

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.
