I am trying to learn lisp macros and I generally find
listcomprehensions to be elegant and they dont exist in lisp.
This has to be a macro right? Cant be a function?
Yes, it has to be a macro, if you need it fast and if you want your own
syntax, like used for list comprehensions in other languages like Haskell.
A nice example is this one, which was presented at ILC2007:

Maybe you should take a look at Liskell, too. Liskell is a new Lisp syntax
frontend for Haskell, so I assume it implements list comprehensions and it
might help to find a good Lisp-like syntax.
