interesting collection… I would propose the raku sequence op `…` as a ternary, for example: 1,2,3 … Inf; #(1,2,3,4,5,6…) arithmetic sequence 1,2,4 … Inf;

interesting collection… I would propose the raku sequence op `…` as a ternary, for example: 1,2,3 … Inf; #(1,2,3,4,5,6…) arithmetic sequence 1,2,4 … Inf; #(1,2,4,8,16,32…) geometric sequence so looks at all three of the operands to work out the result
