I think:

define-library (example grid) . <*
export . (
  ; constructors
  make
  ; accessors
  rows cols ref
  ; traversers
  each
  ; setters
  rename(put! set!)
)
import (scheme base)

...
*>

..makes more sense.  The convention settling across Scheme's seems to
be that libraries are named like so: (collection sub-lib ...), so
using "scheme(base)" or "example grid" might be bucking conventions a
little, since the "standard" names would be written "(scheme base)"
and "(example grid)".

Of course, t-expressions kicks parentheses conventions **hard**, so
well, whatever anyway (^^)
