Message:
I've added [tcl::unsupported::representation] (takes a single argument)
which reports the representation of an object. It's deliberately made
awkward to use as a condition test (don't do that!) and it's unsupported,
but does let you probe what is going on.

Given that it's unsupported (and any attempt to support it is going to be
really resisted) I'll close out the TIP as Withdrawn.

Detecting shimmering is certainly the most important usage.
Tcl is famous for its rich introspection features. I believe
that,
if there's a simple means to complete these features further,
it should be done. The internal representation is just one of
them.

If the desire for this information is to optimise code by
detecting shimmering, then it would suffice to create a
well-known extension which provides it.

Perhaps I'll throw a simple critcl thing up on the wiki.

Donal, you're right, it's very similar to TIP#117. I didn't
see that TIP.
Nevertheless, I don't understand the reason for its withdrawal.

Looks like TIP#117 to me, which was withdrawn on the grounds
that it would be more used than abused.
