Note that this looks like a workalike for a2, for the domain you
have choosen:
a2b=: 1 :0
:
x u (}.~ <:@#) y
)
Or, if the shape isn't really an issue for you, you could
replace that parenthesized expression with {:
That said, I think I know how to do the sort of recursion you are
trying for, I just need to consider things a bit more carefully.
