plus any time you want you can `GenericPrototype.toArray =
function(){return Array.from(this)};` ... no need to put in specs your C#
flavor, somebody else Python flavor, Ruby, Java, or Haskell ... JS would
look like the tower of babel ^_^note: it kinda does already in specs V6 and early 7 On Thu, Aug 29, 2013 at 9:01 AM, Forbes Lindesay <[email protected]>wrote: > This all seems fair enough.
