SelfGOL accomplishes these feats in under 1000 bytes of standard Perl,
without importing any modules, and without using a single if , unless , while , until , for , foreach , goto , next , last , redo , map , or grep . To do all that in under 1K of code, it relies on some extreme
programming techniques, and on many of the obscure backwaters
of the Perl syntax. This talk explores both.
