Slides for the presentation "Back to The Future: Algol68" I made in FSCONS 2011.
Back in 2011 I wrote what I think is the only "canadian" GCC front-end ever written, i.e. a compiler front-end written in language A, implementing a language B, in GCC that is itself written in C. Behold the brainfuck GCC frontend written in Algol 68!
a68-mode is an emacs major mode to edit Algol 68 programs. It provides basic syntax highlighting and context-sensitive indentation.
