I think the reason that we don't all instantly agree on the direction
is simple: the operation is not directional. The operation is
composition; the operands are not types but components of a type.
Thus I think a 'natural' feeling syntax won't be arrow-ish.
Ultimately Allen is attempting to provide some of the benefit of
setting __proto__ while avoiding some of its problems. Perhaps a
syntax closer its home? eg something like a set-prototypeOf property
{ ^:MyObject.prototype, a:1,b:2}
[0,1,2,3,4,5].^ = appArrayBehavior
let subclass = Function.create(superclass, {});
var p = /[a-m][3-7]/.^ = newRegExpMethods;
