This is wrong on so many levels!
I agree, but
Proposal:
Add System.Info.isWindows :: Bool
is hardly better, because this opens the door to political issues (why not have isLinux, isFreeBSD, isNetBSD, ...?) And I'm not even sure returning True for every Windows incarnation is the right thing in most use cases. In general you want to test for APIs--not the OS per se. I am much for an ADT instead of an unstandardized String, but having a battery of is<OS> is not a solution -- a library/program should be able to decide for itself how much info about it's environment it needs. (e.g., isWindows on cygwin depends really on what information you need, like for calling certain libraries, or just have a different UI style, etc.) / Thomas
