A quick google and some personal testing showed me that the former
doesn't work and the latter does, because bash doesn't interpolate
variables in the middle of another variable like that; you need to use
eval to make a second pass for it to work. Rather hacky, though, and I
see no point in using it over the conditional construct proposed
earlier — I just hate to see a suggestion that doesn't work out there.
