This does not look correct: assuming my knowledge of calc is correct,
the result should be the scalar 3 multiplied by each of the vector
elements.  I don't understand how =(3, 6)= can be the output of =3 y=...

The strange thing is that this doesn't work at all for me (with git as
of a few minutes ago): I still get the error message

: byte-code: Bad format in variable contents: Expected a number

However, if I put the vector in double quotes, it works:

--8<---------------cut here---------------start------------->8---
  #+begin_src calc :var y="[1 2 3]"
3 y
  #+end_src

  #+results:
  : [3, 6, 9]
--8<---------------cut here---------------end--------------->8---

*but* if I subsequently remove the double quotes, it doesn't work and if
put them back, it no longer works either.  I am confused...  there's
like a hysteresis loop in org babel :(

Any suggestions on how to debug this are welcome, of course.
