// In CON, the dangling else ambiguity is resolved in a very peculiar way:
|
|
// A cascade "ifP1 ifP2 ifP3 Stmt1 ... else Stmt2" is considered as if the
|
|
// predicates P1, P2, P3, ... are combined with a logical AND.
|
|
// So effectively, there is no ambiguity at all, and one of Stmt1 and Stmt2
|
|
// is guaranteed to be taken.
