Enum LookupLeft 

pub enum LookupLeft {
    AnyRank,
    VectorOnly,
}

What dyadic ⍳ takes on its left.

The APL2/ISO line, which GNU APL implements, looks a cell up among the items of a left argument of any rank, so (2 3⍴⍳6)⍳5 answers and a scalar left argument is a one-item table. Dyalog takes a vector alone and gives a RANK ERROR for anything else, scalars included.

Variants
