Hmm... Of-course, all the FILES|SECTION|RDEPENDS|RRECOMMENDS_${PN}* in
bitbake.conf actually on the current semantics.
Perhaps it would make sense to add a new syntax for using immediate
expansion in the variable name, fx.
BAR_$${FOO} = "6", which would then assign "6" to the variable name
expanded immediately.
