I've been teaching OCaml to university students in Beijing. I believe
they'd feel more comfortable if the error messages were in Chinese. Has
anyone thought of implementing multi-language strings in the compiler? So,
say with the setting of an environment variable, the compiler user could
receive errors and warnings in their preferred language. I know it would
require a lot of translation work (crowd sourced?), but the internal
language abstraction mechanism would need to be there too.
