is the more clean and minimalistic dialect, and is what's mostly used in
academic circles.

Scheme itself has umpteen different "implementations", which share most of
their fundamentals, but have slightly different extensions and interact with
the operating system differently. One major implementation used to be called

familiar with one of them, it's not difficult to move between it and the
