I suspect it is intended. You certainly wouldn't want those interior
forms evaluated at reader time. To be more like literal vectors and
maps, eval would have to know how to handle each record type, find the
forms contained in the values, evaluate them, and build a new record
with the results. Off the top of my head I don't see why this would
be impossible, but it may not be desirable.
