+  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".
