As of 5b028f527f2c487a5f4196fdf3cfc7a2acef74ff the syntax of a pattern
consisting of a nullary tag has changed to omit the trailing '.' That
is: now we write
alt x { some(_) {} none {} }
instead of
alt x { some(_) {} none. {} }
To make this change possible, the typechecker now forbids local
variable names that shadow the name of a tag that's in scope.
Cheers,
Tim

actions or lack of action.” -- Audre Lorde
