Hi Georg,
If you run it, you'll see it produces the result you would expect:
IN: scratchpad 1 2 3 4 4 narray .
{ 1 2 3 4 }
The reason it "produces a quot" is that it is implemented as a macro that
generates a quotation to do the work (in this case with a stack effect
consuming 4 items and producing 1 array).
Try this;
[ 4 narray ] expand-macros
You can also try this:
[ 4 narray ] infer
Hope that helps!
Maybe our documentation should say something about the quot, but it makes the
stack effect a little busy:
MACRO: narray ( n -- quot: ( n.. -- array ) )
