Z←L~R

returns a subset of L consisting of those elements in L which do not occur in R.

L is a scalar or vector, else signal RANK ERROR.

R is an arbitrary array.

Z is a vector identical to (~L∊R)/L.

The result is sensitive to ⎕CT.

This feature is implemented by an internal magic function:

    ∇ Z←L #DydTilde R
[1]   Z←(~L∊R)/L
    ∇
