- Use single-quoted character literals or `CHARVAL` when you need
a character's numeric value; using strings as numbers is deprecated
- Use `?` to silence a node in warning/error location backtraces
- Use `===` and `!==` instead of `STRCMP`, and `++` instead of `STRCAT`
- Use `__SCOPE__` instead of checking for `..` and `.` separately
- Use `#string` instead of `"{string}"`
- All programs (rgbasm, rgblink, rgbfix, rgbgfx) support `-W` warnings
- `rgbgfx --colors dmg` is short for `rgbgfx --colors dmg=e4`
This was discussed in #706
It also uncovered some off-by-one issues with defining some constants.
A few structs now use rsreset/_RS to define their offset constants, as discussed in #739
