Original idea

From the Ideas list.

Write a “build a programming language” article.

Tree-walking interpreter. Touch on most of the core concepts (lexer/tokenizer, parser, symbol resolver, evaluator). At the end of the article, there would be a functioning programming language, even if only basic.

This could also be a talk: In about 30 minutes, this talk would run through creating a programming language and writing a simple interpreter for it.

This could also become a book. This might be a huge challenge, but opens up the opportunity of writing the programming language in the programming language itself.
