Predicates

exprTypeFlow

Holds if the runtime type of e is bounded by t and if this bound is likely to be better than the static type of e. The flag exact indicates whether t is an exact bound or merely an upper bound.
exprUnionTypeFlow

Holds if the runtime type of e is bounded by a union type and if this bound is likely to be better than the static type of e. The union type is made up of the types t related to e by this predicate, and the flag exact indicates whether t is an exact bound or merely an upper bound.
fieldTypeFlow

Holds if the runtime type of f is bounded by t and if this bound is likely to be better than the static type of f. The flag exact indicates whether t is an exact bound or merely an upper bound.
