-//   Ref: http://www.khronos.org/registry/typedarray/specs/latest/
-//   Date: 2011-02-01
-//
-// Variations:
-//  * Allows typed_array.get/set() as alias for subscripts (typed_array[])
-//  * Gradually migrating structure from Khronos spec to ES2015 spec
-//
-// Caveats:
-//  * Beyond 10000 or so entries, polyfilled array accessors (ta[0],
-//    etc) become memory-prohibitive, so array creation will fail. Set
-//    self.TYPED_ARRAY_POLYFILL_NO_ARRAY_ACCESSORS=true to disable
-//    creation of accessors. Your code will need to use the
-//    non-standard get()/set() instead, and will need to add those to
-//    native arrays for interop.
