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.
