+1 to nullptr, but I didn't nitpick that because the code will be removed by addressing my other nitpick ;))

> ExpressionVisitor and ContextBuilder::findType are modified in order to return the last declaration corresponding to the type of an expression, if any. For instance, "a" is an expression of type int and its corresponding declaration is the "var a;" of the previous paragraph. This is needed because there is no way to find the declaration that "owns" a type, as it is possible for context.
