The language much of this house's tooling is written in. A named tool rather than a concept.
Named at the language's conception in 1989 by its creator after the British comedy troupe Monty Python's Flying Circus, deliberately not after the snake, which is why the language's own documentation is full of jokes rather than reptiles.
The language much of this house's tooling runs on, named for a comedy troupe rather than a snake. A tool with a chosen name, not a descended one — irreverence built in from the start.
