Is it true that in Factor the quotation has access to the parent function's
local variables?
Over on comp.lang.forth Bernd Payson has said that in Factor quotations do not
have access to the parent function's local variables --- he uses this argument
to justify that his "quotations" (just :NONAME with some syntactic sugar) don't
need to have access to the parent function's locals.
Anyway, in LOTD my quotations have access to the parent function's local
variables.

In addition to the other suggestions, maybe you really want swons?

in Scheme I can evaluate (list ?()) to get ?(())
as a nested null list
Factor supplies nil (+nil+) but I can?t seem to get the above using cons, 1list
etc.
is this not the natural way to do this in Factor?

yes. Which is the same as ```nil 1list```.
