Construct a ModuleName from a valid module name String.

This is just a convenience function intended for valid module strings. It is an error if it is used with a string that is not a valid module name. If you are parsing user input then use Distribution.Text.simpleParse instead.

The individual components of a hierarchical module name. For example

 components (fromString "A.B.C") = ["A", "B", "C"]

Convert a module name to a file path, but without any file extension. For example:

 toFilePath (fromString "A.B.C") = "A/B/C"
