Hm, I don't see this -- string.py imports just fine.  There's no
_idtable in my copy of string.py?!?!

These should all be fixed.

Interesting.  One more reason to drop string exceptions sometime in
the future.

> * struct.pack('s') doesn't like Unicode as argument

Fix it.

Fix it, but with low priority (the expectation is that sre will replace
pcre in 1.6a3).

> * regex doesn't work either because string objects are hard-coded

Don't fix (regex is obsolete, only kept around because it used to be
very common).

Yes, this has 8-bit string written all over it.  It really should be
using the buffer API rather than requiring strings!

> * cPickle.loads() doesn't like Unicode as data storage

Hm, hard to fix.  Again, it really should use the buffer API, but it doesn't.

> * keywords must be strings (f(1, 2, 3, **{'a':4, 'b':5}) doesn't work)

How hard would this be to fix?

Not very important.

What I said. :-)
