I don't know how to write a test for this off the top of my head, but
Iterator and DynLexPad don't play well together atm. When I tried, I
got this error:

elements() not implemented in class 'DynLexPad'

Is there an easy way to make an arbitrary hash-like PMC (DynLexPad,
NameSpace, etc.) play well with iterator?

Tcl needs to be able to iterate over the keys to return a list of all
the variables in the current procedure/lexpad. (See [info vars])

A nice cage task would be to write a test demonstrating the use of an
iterator in this case.

As of r30844 there's a TODO'd test for this, but some work will need to
be done to make DynLexPads (and LexPads, incidentally) iterable. Since
DynLexPads are based on Hashes, I imagine most of the work will be in
adapting get_iter and get_*_keyed.
