checkpoint - extend constructed types w/ expression arguments, new 'lens' type operator, which can wrap evaluations of other types, + provide a name/args. e.g., bitmap(256, 256) <- (uint8 *), as a well-formed type. this also is the first step to collapsing all 'expression introspection' paths, and making sure they all compose properly.
