Hmm, certainly in the area the lack of proper testing and debugging. 

>From personal experience with porting things such as Tcl/Tk to machines on
which signed vs. unsigned matter; I fear that this opens up a whole can of
worms. Whereas a normal char (or signed int), though arguably wrong,
gives expetable behavour. Given the boxes most of us have access to I
would have trouble seeing how to debug and test that.
