Be careful with this; this form is not documented properly [1]. The indices
produced by the verb in verb} y and x verb} y are into /the ravel/ of y.

(Note that 2 is a noun and 2: is a verb)
Of course, the ravel of a rank-1 array is a no-op (i.e. the ravel of a vector
is the vector), so this isn't a problem in Matthew's use case (though I might
slap a "1 on his verb, prophylactically).
I personally would use ' '&=`(,:&'0')} ' 5\ 3\2004' , but that's a matter of
taste.
