Even for bad/inexperiences/stressed/inattentive/... developers, Go is a minefield.

Just a trivial example: trying to use append(x, y) without re-assigning to x? Congrats, it will compile without warnings, work fine for a while, then at one point append will reallocate and bang, have fun letting the newbie debug that on a Friday evening.

I don't understand what you mean by this.

  [~] $ cat main.go 
  package main

  import "fmt"

  func main() {
   x := []int{1, 2}
   append(x, 3)
   fmt.Println(x)
  }
  [~] $ go run main.go 
  # command-line-arguments
  ./main.go:7:2: append(x, 3) (value of type []int) is not used

and if you assign the result of the append to something else, x is unchanged.
