Ultimate Golfing Simulator 3000 is a family of programming languages designed by User:rdococ.

Semantics

For every brainfuck program, there is a dialect called Ultimate Golfing Simulator 3000(xxx) with the brainfuck program replacing xxx. If the program is non-empty, a syntax error is reported. Otherwise, the particular brainfuck program corresponding to the dialect is executed.

Examples

As you can see, this language family absolutely dominates code golfing challenges.

Computational Class

Some of the languages in the Ultimate Golfing Simulator 3000 family can simulate a Turing machine and are therefore ℒ-equivalent. Besides that, none of them are Turing complete.
