  The callbackfn return does not change the instance
info: |
  22.2.3.25 %TypedArray%.prototype.some ( callbackfn [ , thisArg ] )

  %TypedArray%.prototype.some is a distinct function that implements the same
  algorithm as Array.prototype.some as defined in 22.1.3.24 except that the this
  object's [[ArrayLength]] internal slot is accessed in place of performing a
  [[Get]] of "length".

  22.1.3.24 Array.prototype.some ( callbackfn [ , thisArg ] )

  6. Repeat, while k < len
    ..
    c. If kPresent is true, then
      i. Let kValue be ? Get(O, Pk).
      ii. Let testResult be ToBoolean(? Call(callbackfn, T, « kValue, k, O »)).
