It looks like I still don't understand how this works. Why wouldn't
the simpler

   (let ((synopsis (lambda (_) _)))
     (make-gcc-toolchain gfortran #:synopsis (synopsis "=E2=80=A6")))

be sufficient? And is there a good reason to prefer such constructs
to

  (define-public gfortran-toolchain
   (package (inherit (make-gcc-toolchain gfortran))
     (synopsis ...)
     (description ...)

which I think expresses the intention more clearly?

Cheers,
  Konrad
