`type-of' should be ok in most cases, but I'm looking for an alternative
for cases where e.g. `type-of' just says `cons' whereby the objects are
actually very different things that are identified with a tag as first
element or so.  It's just that these are not represented with "official"
classes defined with defstruct.  If the code in question doesn't use
methods but just a `cond' to distinguish I'm lost anyway but if it uses
methods than I could use the signature of the chosen method (for a
specified generic name) for hashing, or the signature of the most
specific method implementation.  Then the color would only change if the
hierarchy of implementations changes, and in that case a changed color
would be acceptable.
