// 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.
