- Corrected the indentation issues in the lux files.
- Temporarily reverted back to forward apply-analysis.
- Fixed an error in lux.base/show-ast.
- Reader now only returns a tuple instead of a full-blown #Meta variant.
- Reader now doesn't cut the strings that it reads. Instead, the "cursor" just moves around, indicating where to read.
- Inlined some calculations that previously relied on try-all%.
