Besides OpenGL, there's also SDL2, which can't be faithfully represented because of partial casing, eg SdlError enum, vs say SDL_Error.
On the other hand, recently working with Ada, I see there's a lot of case insensitivity there too, which is a point in it's favor: [https://en.wikibooks.org/wiki/Ada_Programming/Lexical_elements#Character_set](https://en.wikibooks.org/wiki/Ada_Programming/Lexical_elements#Character_set) On the gripping hand, I'd really like to be able to eg, go through C tutorials on C libs, without having to - while going through those tuts and docs - also rename a lot of identifiers over to the renamed Nim versions that wrap those lower level C libraries.
