Add the -XQualifiedDo flag #468

Closed facundominguez closed 4 years ago

facundominguez commented 4 years ago

This task is about having GHC accept the QualifiedDo flag and do practically nothing with it.

When the AST is updated, GHC can produce an error message if a qualified do appears in the program and the flag is not enabled.

I'm creating a new task to do the error message. It depends on the parser and the ast to be able to test it.
