Are guile's macros safe to always use that way?  In libguile/__scm.h
the SCM_ASSERT definition is conditional on SCM_RECKLESS and appears
unsafe without the block.

In NEWS it is mentioned that SCM_RECKLESS has been “removed
completely” between 0.6 and 0.8, so I wonder if this instance was
missed.  The conditional in __scm.h dates to 1996.

In any case, applied your suggestions and reattached; user of
-DSCM_RECKLESS beware.
