+A _block expression_ is similar to a module in terms of the declarations that
+are possible. Each block conceptually introduces a new namespace scope. View
+items can bring new names into scopes and declared items are in scope for only
+the block itself.
+
+A block will execute each statement sequentially, and then execute the
+expression (if given). If the final expression is omitted, the type and return
+value of the block are `()`, but if it is provided, the type and return value
+of the block are that of the expression itself.
