If:
   d =: %&2 
   d 16
8
   d d 16
4
   d d d 16
2
   3 d 16
2

then:

   e=: 13 :'y%2'
   e 16
8
   e e 16
4
   e e e 16
2
   3 e 16
8

Shouldn't  3 e 16 be a "domain error"  or "Why is  3 e 16  equal to  8  ?

Maybe this will help with  u&n y  and  x u&n y

     d =: %&2  NB. divide by 2
    d 16
 8
    3 d 16  NB. means d d d 16
 2
    d d d 16
 2
