You're looking for (node-list-error str nl) from 10.1.4.

One thing I'd like is to be able to indicate the calling code in an
error report.  This would be useful in functions that find they've
been called with the wrong argument types - they would be able to
behave like primitives in that respect.  I suspect that implementing
that behaviour would cause tail-call elimination to be less effective
(like using jade -G), so it's not on my "real" wish-list.
