Comment (by ashinn):

 FYI, as discussed on the Chibi behavior is non-standard permissive
 matching, which can be disabled at compile time with
 `-DSEXP_USE_STRICT_TOPLEVEL_BINDINGS=1`.  This was intended to be more
 convenient, and matched the behavior of some other implementations at the
 time (I believe Chicken and Gauche), and because I hadn't seen a real-life
 example where it caused a bug.

 This causes confusion, however, when comparisons like this come up, and
 since Chibi is the R7RS reference implementation I will reverse the
 default behavior.
