Nanopass Framework: Clean Compiler Creation Language | Hacker News

The article argues that compilers are easier to build and maintain when split into multiple passes.

Using the Nanopass Framework, it notes that the right number of passes and intermediate representations depends on the source language.

Scheme is presented as a good fit for a staged pipeline with parsing, macro expansion, lowering, CPS transformation, closure conversion, and code generation.

The main takeaway is that language-specific compiler architecture can improve readability, maintenance, and optimization strategy.
