The problem with making this RFC do the lossy thing is it then removes one key advantage of it: that this RFC provides a measure of strictness. Without that, we have no real compromise proposal, and we might as well introduce a second set of “strict” type hints. The whole point of the current behaviour is that it compromises between the weak typing and strict typing camps; doing what zpp does is giving in to the former camp, and then it’s not a compromise any more, is it? -- Andrea Faulds http://ajf.me/
