[plt-scheme] hey ! where's send super

Don't you need to inherit and rename the field as in (inherit (rename
[super-write write])) or something like that?

  For list-related administrative tasks:
  http://list.cs.brown.edu/mailman/listinfo/plt-scheme

Use `rename' to get access to the super.

  (rename [super-write write])
  (define/override (write)
    (printf "my writing\n")
    (super-write))
