## Naming conventions
leading underscors `_` indicate a "private" label/variable, that is meant for internal use within the module only.
### Labels
- **scopes**: snake case
- **subroutines** and **variables**: snake case (`scope::(_)fname_snake_case` or `scope::(_)varname_2`)
- **macros**: camel case (`(_)GoodMacroname`)
- **constants** (eg. in ROM): upper case (`scope::(_)NICE_SYMBOLNAME`)
