I suppose it's this error?

ERROR in "string-cursor->index": invalid type, expected String-Cursor: 1

The "1" is from this

> (string-cursor-next ABC 0)
1

I think chibi does not follow the srfi here. The document for
string-cursor->index says " If the argument is already an
index/cursor, it is returned unchanged. ". So chibi should accept "1"
and return it. But it throws an error instead.
