Appose | u&:v _ _ _ |

`&:` is equivalent to`&` except that the ranks of the resulting function are infinite; the relation is similar to that between`@:` and`@` .

For example:

       a=: 'abcd' ; 'efgh'
       b=: 'ABCD' ; 'EFGH'

       a
    +----+----+
    |abcd|efgh|
    +----+----+

       b
    +----+----+
    |ABCD|EFGH|
    +----+----+

       a ,&:> b
    abcd
    efgh
    ABCD
    EFGH

       a ,&> b
    abcdABCD
    efghEFGH

       > b. 0
    0 0 0

       , & > b. 0
    0 0 0

       , &: > b. 0
