True, macros can confuse people not used to the concept.

For example the DEFUN macro: (defun plus (a b) (+ a b))

'plus' is in the function namespace, even though it is in a non-function position.

Strange, isn't it?

That's true. But it doesn't even try, because the 'succinctness and elegance' of currying without adding some syntax is a non-goal for Common Lisp. Lisp has always preferred one expression for each function call and over the years it added complex argument lists (variable number of arguments, optional arguments, keyword arguments, ...).

Personally I don't miss things like 'automatic' currying, since they are making the code harder to read (-> currying is not explicitly visible in the source code) and debug.
