Re: [RFC]Discuss] Syntax for Arrow Functions

> it could be a single symbol instead of two even if this can be done without parser ambiguity, it suffers from visual ambiguity with the assignment operator. consider what this would look like if the expression itself uses the assignment operator... f($x) = $y = $y + $x; versus something like: f($x) => $y = $y + $x; even that is visually ambiguous when used in arrays though: $a = [ "foo" => f($x) => $y = $y + $x, ]; also unreadable. even if the parser can cope, I think we need some other symbol that isn't visually ambiguous when used in these contexts?
