ESON

ESON is an Esoteric Knowledge Representation Format designed to be so easy to parse it melts Nazis' faces and burns out their eyes. The acronym "ESON" actually isn't an acronym, because it doesn't stand for anything.

Design
ESON is a stack-based language for encoding a generalization of JSON-like data in a simple way. It allows for Lists, Sets, Tuples, Maps, Ordered Maps, Symmetric Maps, Binary Trees, General Trees, and optionally graphs. Being a stack-based language, the commands are almost entirely procedural. It is not Turing-complete, nor is Turing completeness even applicable to it, the same way TCness is inapplicable to XML.

Lexing and Parsing
Lexing ESON can be done by simply splitting it by spaces. Parsing is done with a FOR loop iterating through the commands and executing them.
