References finds all of the references in the given set of traversals, returning diagnostics if any of the traversals cannot be interpreted as a reference.

ReferencesInBlock is a helper wrapper around References that first searches the given body for traversals, before converting those traversals to references.

ReferencesInExpr is a helper wrapper around References that first searches the given expression for traversals, before converting those traversals to references.

ParseRef describes the signature of a function that can attempt to raise a raw HCL traversal into a reference.
