The last one, roughly: see the "pconvert.ss" MzLib library. The
`print-convert' procedure converts a value v1 to a value v2 such that
when v2 is written, the output can be read back as an expression to
produce v1.

You'll want to set the library's `constructor-style-printing' parameter
to #f before converting a value for display.
