The author demonstrates the second Futamura projection by specializing a partial evaluator with its own interpreter, producing a compiler that directly transforms Brainfuck programs into residual code without ever running the interpreter. The resulting compiler closely resembles one written by hand years earlier, validating the theoretical approach.
Background
The Futamura projections, introduced by Yoshikazu Futamura in 1975, are foundational results in partial evaluation showing how specializers can be composed to produce compilers and interpreters. This blog continues the author's exploration of building a Brainfuck compiler via partial evaluation.
