Not sure if this might be related.  With guile-3.0

  (use-modules (oop goops))
  (define x close)
  (define-generic x)


  $ guile-3.0 -s test.scm
  ;;; note: auto-compilation is enabled, set GUILE_AUTO_COMPILE=0
  ;;;       or pass the --no-auto-compile argument to disable.
  ;;; compiling /home/rlb/test.scm
  ;;; /home/rlb/test.scm:5:0: warning: shadows previous definition of `x' at 
  ;;; compiled /home/rlb/.cache/guile/ccache/3.0-LE-8-4.2/home/rlb/test.scm.go
