What's your `print-dup` for instants print them as? The way compilation
for these expressions is going to work is:
(a) The initial form will be read using the configured *data-readers*,
handing the compiler a form with a literal instance object.
(b) The compiler will generate code to create that literal; when the
literal value isn't of a type the compiler knows how to emit directly, it
emits code to round-trip back through the reader at run-time, embedding the
`print-dup` representation of the object as a string.
If `print-dup` prints in such a way as to discard the offset, away it goes.
