Comment by Solomon Ucko (JIRA)

Based on https://github.com/apple/swift/blob/7123d2614b5f222d03b3762cb110d27a9dd98e24/docs/ABI/Mangling.rst, here is my guess for the mangled name is supposed to be parsed:

Based on the output, it seems like the original name is Curses.CursesError.failure(function:returnValue:arguments🙂, which matches with the identifiers in the mangled name.
