Note that you this expression has three nouns:2, 1 and i.9

This means that u can not be a verb.

If you want a verb (I think of 'u' as indicating a verb), you should
make 2 and 1 be items in a list.  This should cause no difficulties
if they are the same type (numeric -- as you have shown here).

   2 [EMAIL PROTECTED]({:@[)`]} i.9
0 2 2 3 4 5 6 7 8

If the "2" argument were some other type, you could still
make this work (box the items and unbox them when
using them).

On the other hand, Henry's expression is more concise.
