In that case can the documentation, eg in the ghc user guide[1] be
updated to use the new name. It's jolly confusing to go looking for the
extension name corresponding to the extension. The ghc user guide
section on it calls it generalised and mentions no flag or extension
name. We initially thought that the extension had never been registered
and I only found it by accident when looking in the reference section of
the ghc user guide on flag names[2] I noticed that "transform list
comprehensions" actually links to the section on generalise list
comprehensions.
