I'm so sorry if this confuses you, but I enjoy composing (superfluous)
phrases like this. I hope you don't mind. :-)

Several interesting solutions, thank you.
I understand the first 2 examples below:
+:/ 1 2 3
|domain error
2 */ 1 2 3
2 4 6
this is definitely less clear:
2&*/ 1 2 3
24
I guess this comes fromhttp://www.jsoftware.com/help/dictionary/d630n.htm
(dyad bond):
2 (2&*) 3
12
At first I hated this form as needlessly confusing, but a fantastic feature is
that it turns ^: into a verb, and so as you have done, can apply a modifier to
it:
1 1 2 (2&*)"0 ] 12 2 3
24 4 12

the right hand side must be boxed. Unboxing at end, just there for display.
Should not assume that it is possible for input.
What the above is doing is if/for a cell that is equal to 2, double the
previous cell.
To get it to work, I've had to generate a full n x n table, and then take the
diagonal. Is there a better tacit way that avoids n x n table?
