...we could do that, couldn't we? If the list of variables expanded
is limited to a standard expected list (ie all one sees in 'man 5
ebuild' plus say, MY_{P,PN,PV} as those are also fairly common.
I've never compared the efficiency of bash substitution compared to
say, pipe'ing through awk or sed, though, so i don't know if this
method would be better or worse..
