I get this (or similar) from lily:

Regardless of the fact I use an 8-element list or a list of 4 pairs, or a list
of 8 pairs,
or anything else in list, including even strings...
So: I would REALLY appreciate very much any EXAMPLE of using such statement.
(sb. said "one picture says more than a thousand words", i'd say "one
example...")
It looks as if you're making mistakes with Scheme quoting. You should
use something like
(list 'bezier-sandwich (list 'quote '(0 . 2) '(1 . 4) ... ))
or
'(bezier-sandwhich (quote ((0 . 2) (1 . 4) ... )))
I guess.
You need an extra quote because the expression of a stencil is evaluated
another time in the back-end.
