INTERCAL::64

Old Dog. New Ticks.

The language that should not exist just got an upgrade. 64-bit arithmetic. A complete system library in pure INTERCAL. A real debugger in VS Code with an AI assistant that heckles you. Torture yourself with crazy syntax, confuse your friends by pretending to know what that code does, and find out what happens when you give a 1972 joke language a serious development environment.
