I'd like to be able to define lambdas using common Lisp syntax, in Clojure. For example:

(lambda (myarg)
  (some-functions-that-refer-to myarg))

This needs to result in the same as:

#(some-functions-that-refer-to %)

In my case, I know I'll always have exactly one arg, so perhaps that simplifies things. (But it can be called anything -- "myarg" or whatever.)

I suspect a workable solution is to "(defmacro lambda ...". If so, I'm not sure of the best way to proceed. How to cleanly translate the arg name to %? And how to end up with the correct function?

Or, is there a simpler solution than writing my own macro that actually re-implements Clojure's... lambda?
