Nico and I spent some time looking at non-eval strategies, and weren't
able to come up with anything that had all the right semantics:
protecting special characters (wild cards, white space, newlines, et
cetera) in values, while allowing multiple values to be returned and
processed unambiguously.
The big problem was that (simplifying)
echo `some_command`
processes shell wild cards in the output from some_command, with no way
to quote them, and
echo "`some_command`"
does not allow unambiguous representation of multiple values,
potentially with embedded white space. I think there were other issues too.
