- No need for "unidentified" hex values in common idioms like "ld c, a / ld b, 0" or "adc 0"
- VWF char coordinates are masked with %11111000 and %00000111
characters as 16-bit words
The main gotcha with this is that you won't be able to use commas
without escaping them, until the rgbds lexer gets a proper upgrade.
