RFC Esolang – RFCs as executable programs

RFC Esolang is a programming language in which the specification document is the source code.

Requirement levels like MUST, SHOULD, and MAY act as control flow. Section numbers define labels. Packet-diagram labels serve as registers.

Executing RFC 9379 outputs the powers of two. Pre-existing RFCs MAY parse as valid programs, forming a historically accidental standard library.
