Hi Bart,

  This is a bit expensive in the general case -- i.e. having to construct
an object every time I want to do a type check (and other objects may have
expensive constructors).

  Now, technically, we could prebuild a gigantic map of "singleton objects"
representing one of each type, i.e.

(let [obj ... ]
  (defn is-obj-type? [...]
     ...))

but this still feels slightly hacky.

  I appreciate the effort though. :-)
