export in syntax-rules

[Kevin Ryde]

In guile 1.6.1 on a recent i386 debian, I thought to use "export"
inside a syntax-rules in a module definition, for instance

    (define-module (abc def)
      #:use-module (ice-9 syncase))

    (define-syntax foo
      (syntax-rules ()
        ((foo name)
         (export name))))

    (define x 123)
    (foo x)

But I got an error,

    ERROR: In procedure variable-ref:
    ERROR: Wrong type argument in position 1 (expecting variable): #f

Is this sort of thing meant to work, or have I made some basic error?

(I was looking to make "-public" versions of some macros.  I got the
effect I wanted with a procedure->macro, but just wondered if the
syntax-rules style was valid.)
