@ -4,7 +4,7 @@ Layers in the 1xx series are in bare SubX, without any syntax sugar. They are
intended to be used by the phases of the self-hosted translator to replicate
the functionality of the C++ bootstrap:
apps/hex.subx
apps/survey.subx
apps/survey_elf.subx
apps/pack.subx
apps/dquotes.subx

all the different syntax sugars and what they expand to.
* Code unique to phases of our build toolchain:
* Core SubX: `hex`, `survey`, `pack`, `dquotes`, `assort`, `tests`
* Core SubX: `hex`, `survey_elf`, `pack`, `dquotes`, `assort`, `tests`
* Syntax sugar for SubX: `sigils`, `calls`, `braces`
* More ambitious translator for a memory-safe language (in progress): `mu`
