// print, pprint, and tostring
//
// This module implements the heart of the lua 'print', lua 'pprint', and lua
// 'tostring' functions. Note that we have to override the lua builtins 'print'
// and 'tostring' for two reasons:
//
//   * We need to suppress the printing of table addresses, for determinism.
//   * We need to channel the output to a PrintBuffer in the world model.
//
// Note that the actual lua 'print' and 'pprint' routines aren't defined in this
// module, they're in the World module, because they send their output into the
// PrintBuffer of the world model.  But all the tricky code to implement 'print'
// and 'pprint' are in this module.
