<div>I'm tentatively in favor. I think this solves a real problem, and I like that it's re-using the same syntax that we already use to talk about functions in documentation and discussions. I'm mildly concerned about the visual ambiguity, and about the fact that if the parser encounters `foo.bar(baz: qux` it doesn't know yet if "qux" is supposed to be an expression (because it's a function call) or just a bare identifier (because it's a function reference), and it can't know that until it sees a colon. I'm also mildly concerned that this feature will make it impossible to ever introduce a single colon as a valid character in an expression that's not surrounded by delimiters (e.g. dictionary literals are fine because of the delimiters), but I'm not sure if that's something we'd ever want to do (note that introducing a double colon, e.g. ::, is fine because that's not legal in a function reference).<br></div>
<div> </div>
<div>Given that I think the ambiguity can be dealt with, and I don't think the visual ambiguity is particularly bad, and I'd like to see this problem have a solution, that's why I'm tentatively in favor of it.<br></div>

<div>I have not. The languages I can think of that have similar types of function references don't have infix method names (or don't even support overloading).<br></div>

<div>A quick reading.<br></div>
