At first glance it may not be obvious that the generalized type is sound, but if the programmer starts out with the simpler type declaration, the type errors will point out the place that needs to be generalized. This can be an unnatural.

Sign up using Facebook. The variance of an existential t ype variable is just the meet of the variances. P erhaps surprisingly, with such a long.

Existential subtyping does not conclude subtype relationships for type vari-. Lemma 2 Corollary of lemma 1. Many programming language type systems support subtyping. Intuitively , RList is a read-only list: The language could give special treatment to certain known classes or interfaces in the standard library, thus avoiding a need for declaration-site syntax and checking. As a proposed language change, the enhancement should be accompanied by new JCK-compiler tests.
