I don't mind this API for complex usecases e.g. streaming, but it is 
massive overkill for the simple common case of "I have a list of bytes 
that I want to decode to a string" or "I have a string that I want to 
encode to bytes". For those cases I strongly prefer the earlier API 
along the lines of

String.prototype.encode(encoding)
ArrayBufferView.prototype.decode(encoding)
