// Primordials are used mainly in two ways:
// * Provided to other injected environment scripts

// * Invoked by host to marshall types between environments
//   (e.g. using the VM's Uint8Array to pass a typed array
//   into the VM)

  // and `Function.prototype.call` after it may have been mutated by users.
