What's in the box
Interpreter core ( src/ ) — lexer, parser, tree-walking evaluator. Faithful to the 1985 Agat dialect: Russian-only keywords, case-insensitive identifiers, (* … *) block comments, ; statement separator, three compound types (tuples < > , sets <* *> , records <¤ ¤> ), three-arrow procedure parameter scheme ( name / name => / <=> name ), trailing РЕЗ: for function results.
