No need to use x @a, just assign an empty list. 

  DB<1> @a = qw( a b c d a b )

  DB<2> @h{@a} = ()

  DB<3> x keys %h
0  'c'
1  'a'
2  'd'
3  'b'

Update: Gah, yeah I missed the count part. I agree with below it's a "I want to do iterative task X without iterating" problem. Now I'm going to take a nap before attempting to answer anything else . . .
