Brainfuck interpreter written in Opendylan programming language.

This is an exploration of Opendylan features (mainly multimethods) and is not trying to be "as fast as possible".

where:

• program is a brainfuck program
• optimization-level is a number between 0 and 4 (default 4):

  • 1: Remove comments
  • 2: Group similar instructions (e.g. ++ becomes +2)
  • 3: Replace pattern [-] with a reset to zero
  • 4: Precalculate jumps (e.g. [+>] becomes [3+>]0
