Buggy, half-written version of the Algorithmic Language Algol 60.
I wanted to learn Algol, as it is the ancestor of so many great programming languages.
But I'm lazy.
So instead of finding a working implementation, I started implementing it based on the Revised Report on the Algorithmic Language Algol 60.
For educational purposes, enjoy!
Pull requests with sample Algol code or bug fixes welcome.
