   @seddonm1 looks great, the 'IN' operator is one of the features I have been missing and thinking about implementing myself but looks like you beat me to it :) 
   my only concern is that the current implementation doesn't appear to make use of SIMD; have you looked into comparing performance against an expression of the form `(eq(array, scalar1) or eq(array, scalar2) or ...)`?
