Improve parsing of type annotations
...
The main motivation of this change is to disambiguate this expression:
[ x : t ]
Before this change, the grammar of the language permitted two ambiguous
interpretations of the above expression:
* The type of a list whose elements are of type `x`, and the type `x` is
itself annotated with a kind `t`
* A 1-element list of type `t` whose sole element is `x`
After this change, the above expression unambiguously parses as a 1-element list
