(define ((f a) b) ...)

(define ((f a) b) ...)

[Thien-Thi Nguyen]

In Guile 1.9 NEWS:

  ** The currying behavior of `define' has been removed.
  
  Before, `(define ((f a) b) (* a b))' would translate to
  
    (define f (lambda (a) (lambda (b) (* a b))))
  
  Now a syntax error is signaled, as this syntax is not supported
  by default.  If there is sufficient demand, this syntax can be
  supported again by default.

+1 for re-instating it, or for adding to NEWS some hint on how to
re-enable support (i take it "not supported by default" means it
is supported with some configuration/switch).

This is used by Guile-WWW (which barring this, is ready for a
fresh "tested with Guile 1.9.x" sticker, and release), and ttn-do,
and probably other stuff i maintain, as well.

Actually support for it was removed entirely. That might have been
appropriate at that point in guile-vm development, but we should
definitely re-add support, via a module.

I'll put it on my list.

Thanks for looking into this.  I look forward to it.

(use-modules (ice-9 curried-definitions))

Perhaps too verbose a name, no?

   (use-modules (ice-9 curried-definitions))

Wonderful news!  Now i have some incentive to return to Guile hacking.
(For a while, i lost gumption when i learned of this missing feature.)
I suppose, first thing to do is to dist upgrade...

   Perhaps too verbose a name, no?

I don't think so.  A module name is typically used once.  Therefore,
more descriptive (which is often goes with verbosity) is better.
