I don't actually mind the syntax that much, `&` on a symbol just gives you a proc for calling `send` on the first argument. What bothers me is the limitations.

I don't actually mind the syntax that much, `&` on a symbol just gives you a proc for calling `send` on the first argument. What bothers me is the limitations. If you're going to have special case syntax to avoid having a useless first argument why not go all the way? Something like this would have made a lot more sense imo: users.map { .name.uppercase + '3' } numbers.map { * 3 }
