Re: Any elegant solutions for this problem?
Thanks both for your answers. @Ben, that seems to do it. I was trying to make it a bit nicer but failed @john, that was my original approach but it does not produce what I want. The result of that is ((foo 1) (bar 10 20) (clown 5)) but I need ((foo 1) (bar 10) (bar 20) (clown 5)) Ryan.
