Re: [RFC] Arrow functions / short closures

Arrow functions are ternary operators to functions. While they are nice and shorten, they can be hard to read at times; considerably to people who aren't used to them which is surprisedly a majority of PHP programmers. Having them optional sure, but not necessary. Feel free to decide between fn() or f() as both are equivalently comprehensible to the same level of minimalism. Anyone considered?
