Hm. I should read through before posting. Another followup to myself:
What I wrote above is not correct.

IDL> a = indgen(5)
IDL> print, 3*a
0 3 6 9 12 15
IDL> print, [3]*a
0

What I was thinking about is that some IDL functions seem to convert
arrays to scalars if they have length one. Cannot find a good example
right now. Hm.
