I think so.  We should be able to reduce the amount of cCode:inSmalltalk: hacks if we get the basics right.  But if it breaks things for you feel free to revert.  Just capture the test cases that break somehow (image, doit, etc) then I can try and fix things later.  I’ll take a look at cStringOrNullFor: today though.
