Why “perma goodbye”?

Go has a similar function declaration, and it supports anonymous functions/lambdas.

E.g. in go, an anonymous func like this could be defined as

foo := func(x int, _ int) int { … }

So I’d imagine in Zig it should be feasible to do something like

var foo = fn(x: i32, i32) i32 { … }

unless I’m missing something?

Anonymous functions aren't the same as lambda functions. People in the Go community keep asking for lambda functions and never get them. There should be no need for func/fn and explicit return. Because the arrow would break stuff is one of the reasons.

    res := is.Map(func(i int)int{return i+1}).Filter(func(i int) bool { return i % 2 == 0 }).
             Reduce(func(a, b int) int { return a + b })

vs

    res := is.Map((i) => i+1).Filter((i)=>i % 2 == 0).Reduce((a,b)=>a+b)
