Dictionaries now incorporated into core and under maintenance.  Any future faults should be raised as bugs (as 
normal.)

sorry about the typo.

The current name is "hashDictionary"

I see that the new Tcl_ObjType
struct, tclDictType, has the name
field value of "hasDictionary".

Why not use the name "dict"
more in keeping with names of
other Tcl_ObjType's in the core?

here is an updated patch, diff'd
from today's HEAD, including
the new files.

A few bugs fixed here, one on
Dict refcounting, and one that
the [dict] command is safe to
give in safe interps.

Note that on platforms where
TCL_WIDE_INT_IS_LONG is
#define'd, the patch for Tcl
Bug 713562 must also be applied
for this patch to work.

This passes all tests in the dict.test
test suite.  I have not checked
whether that test suite covers/agrees
with TIP 111.

Just a note in passing (because I can't be bothered to
reupload all the patches): the structure Tcl_DictSearch does
not need an objPtr member, as it is only ever assigned to in
one place and never compared.  Behaviour should be right though.

Some documentation as part of the TIP itself (since docs 
really form part of the spec, not the impl)

OK, here's a working version of the dictionary code.  You
need the patch, the tests and the C file.  Apply the patch
in the normal manner (:^) put tclDictObj.c in generic/, put
dict.test in tests/, and rebuild.  (Windows users will need
to do a bit of work to update their makefile. I unashamedly
develop only on Unix, though the source itself should be
completely portable.)  Still needs documentation...

All that, plus more comments, plus an implementation of the
[dict] command (pre-TIP state).  More work still needed, but
this is now much closer to being ready for testing...

Here's an (untested) piece of code that implements a
suitable Tcl_Obj and some miscellaneous accessor API
functions.  Much still to do...
