-This expression establishes a lexically scoped block (i.e. an internal
-definition context) in which definitions and expressions may be interleaved.
-Its result is that of the last term (after @scheme[begin]-splicing), executed in
-tail position, if the term is an expression; if there are no terms, or the last
-term is a definition, its result is @scheme[(void)].
