This works:
user=> (defmacro defsym [symbol & body]
`(def ~(eval symbol) [EMAIL PROTECTED]))
nil
user=> (defsym (symbol "user" "bar") 42)
#'user/bar
user=> bar
42
But only if the namespace already exists:
user=> (defsym (symbol "foo" "bar") 42)
java.lang.Exception: Can't refer to qualified var that doesn't
exist (NO_SOURCE_FILE:11)
In general, you probably don't want to do this, anyway. As an
alternative, try using a map.
