// ES3/ES5 implementation of the Krhonos Typed Array Specification
//   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.
