I don't think that's going to make things much more readable, would it?

I did notice one sometimes has to do this with the variant description (variant foo description "bla bla") but 

variant foo description "bla bla" "
	\variant \stuff \here \
"

doesn't really help (me).

I though Joshua's intention was to show that the two procedures print the last known value of foo, not that they complain about an unknown variable because they expect it in their local frame.

Not "which ones", just `uplevel 1 $code`, just like `proc platform` does.
