Details:

The following does not work, but should:

    (define ((f x) y) (+ x y))
    ((f 2) 3)

(the definition gives an invalid syntax error).

Update of bug #25519 (project guile):

             Open/Closed:                    Open => Closed                 

    _______________________________________________________

Follow-up Comment #1:

No, it shouldn't work, according to R5RS Section 7.1.6 "Programs and
definitions", where the formal syntax of a definition is specified as:

<definition> -> (define <variable> <expression>)
      | (define (<variable> <def formals>) <body>)
      | (begin <definition>*)

Thanks,
Ludo'.

Follow-up Comment #2, bug #25519 (project guile):

I'm not sure that's right.  Currying is a well known and unambiguous
extension to the R5RS syntax, and I believe that Guile has supported it for
ages.  There are lots of mentions in the manual, and we have tests for it in
test-suite/tests/syntax.test.

So I think something more specific has gone wrong here.

Follow-up Comment #3:

Hmm, you're right.  The only mention of this behavior in the manual is in the
"define* Reference" node, so I guess the manual will need to be improved as
well.

(Reopening the bug.)
