Hi Sergei,

All tests pass on chibi-scheme.  I ran into the following error when
running them on Guile (after linking 257.sld to srfi-257.sld):

xxxxxx@xanthus$ guile --no-auto-compile --r7rs -L . -l srfi-257-test.scm
%%%% Starting test srfi-257  (Writing full log to "srfi-257.log")
WARNING: (guile-user): imported module (scheme base) overrides core binding `expt'
WARNING: (guile-user): imported module (scheme base) overrides core binding `member'
ice-9/psyntax.scm:2838:12: In procedure syntax-violation:
Syntax error:
srfi-257-test.scm:530:7: _: bad use of '_' syntactic keyword in subform (_ _ _) of (_ _ _)

I'm not sure what the problem is.
