Because letters(ivec) is an array, the concatenation here is an
elemental operation. Suppose, by way of example, that ivec=[1,2,2], so
that letters(ivec)=["a","b","b"]. The concatenation does *NOT*
concatenate the elements of the array together. Instead, it elementally
concatenates the scalar "a" with each element of the array. Thus
"a"//letters(ivec) evaluates to the array ["aa","ab","ab"].

Thank you. I was wondering what was going on with that.

Ditto that thank you, to Richard and to Beliavsky. ;-)

I was aware of vector subscripts, but conflated it with a recent
discussion where a poster expected to be able to use a single vector
of length 2 for both subscripts in a rank-2 array reference, IIRC.
(That one, of course, is incorrect.)

And I'm very thankful for Richard's example above: to my mind, it
makes it much clearer what's going on with vector subscripts.
