Using "eval" here means that you *then* have to be careful about whitespace quoting. For example, if my $HOME had a space in it, EDITOR="$HOME/bin/superemacs" would be broken if you add the extra eval, since the whitespace would be treated as a delimeter on the second lexing. I'd have to figure out how to set EDITOR with the right quotes or backwhacks in it to undo the effect of your eval. Also, eval treats data as code, and if for some reason this should end up in a setuid environment (perhaps as a web application), eval would generate a trivially accessed gigantic security hole. -- Randal L.
