not sure I understand what you say but `["maria",
"marianne"].some(str.contains,
str)` means `["maria", "marianne"].some(function (value) {return
this.contains(value)}, str)` ... no bind nor arrow function needed, the
function `str.contains` is executed with `str` as context per each
iteration. Is that confusing? 'cause that's how
