It'll be nice to have smth like `dsTrueValue` and `dsFalseValue` as standard styles. A dozen syntaxes have (as other styles) it or can use. First things coming to my mind: - YAML, JSON, C++, Js, ... can highlight `true` and `false` values - Python: `True`, `False` - CMake: `ON`/`OFF`, `TRUE`/`FALSE`/`*_NOTFOUND`,... - practically any language w/ boolean data type...
