The syntax permitted in an `interface` is similar to, but different from, that permitted elsewhere. For example, associated constant declarations (`let T:! Type;`) with no initializers are valid in interfaces but nowhere else, and are a different kind of declaration from what a normal `let` declaration would produce both syntactically and semantically. Because interfaces and impls permit only a very small subset of the complete set of kinds of declaration, it's simpler to list only the kinds that are permitted rather than to allow an arbitrary declaration and semantically disallow the invalid cases, and it's also likely to lead to better error messages as we won't try to parse unintended or meaningless things.
