For the sake of clarity while examining alternatives, let's assume for the moment the following infix operators: infix "::" for bind alone as in http://wiki.ecmascript.org/doku.php?id=strawman:bind_operator infix "@" for relationships alone, as in http://wiki.ecmascript.org/doku.php?id=strawman:relationships infix "->" for bind+relationships as you propose here. My question is: If we have "->", how much need would there still be for "::" or "@"? If "->" can subsume the practical need for either or both of the others, that would be interesting. We should postpone any further bikeshedding on which token to use for which meaning until we understand better which ones we actually need. > I know, OOP wins and all, but the downside is that it puts all the burden > onto TC39 for defining a complete iterator API.
