    Many calls to tk.call involve an arglist containing a single tuple.
    Calls using METH_OLDARGS unpack this tuple; calls using METH_VARARG
    don't.  Tcl's concatenation of args was affected; IDLE doesn't start.

    Modify Tkapp_Call() to unpack single tuple arglists.

  Clean up merge glitch or copy-paste error (the entire module was duplicated,
  except the first half even had some more copy-paste errors, referring to
  listcomps and genexps instead of setcomps)

  Dict comprehensions. Still needs doc changes (like many python-3000 features
  ;-). It generates bytecode similar to:

  x = {}
  for k, v in (generator here):
    x[k] = v

  except there is no tuple-packing and -unpacking involved. Trivial
  measurement suggests it's significantly faster than dict(generator here) (in
  the order of 2 to 3 times as fast) but I have not done extensive
  measurements.
