Heya Brian...
Thing is, it's inconsistant. If you don't supply a code block, it doesn't overwrite the vars. If you do supply the code block, the vars "should" (IMO) only be visible within it. I didn't know about the unclobber thing tho. Looking at db_foreach, there's no such issue, or at least no "-unclobber" option. For consistancy's sake, it should be the opposite: if, on the small chance, someone wants the vars visible beyond the block, there should be a -clobber option, and it should also be in loops like db_foreach.
If you like, you can apply the concept from "Apple User Interface Guidelines": don't make (the programmer) remember any more than he has to, certainly not: "so there's a foreach, a db_foreach, a db_multirow, and in only one of those, vars are clobbered outside a supplied block, and then only when it's supplied"... nightmarish... That's exactly the kind of thing that's going to chase devs away.
