// Error codes passed around between file input, tokenizer, parser and
// interpreter. This is necessary so we can turn them into Python
// exceptions at a higher level. Note that some errors have a
// slightly different meaning when passed from the tokenizer to the
// parser than when passed from the parser to the interpreter; e.g.
// the parser only returns E_EOF when it hits EOF immediately, and it
// never returns E_OK.
//
// The public PyRun_InteractiveOneObjectEx() function can return E_EOF,
// same as its variants:
//
// * PyRun_InteractiveOneObject()
// * PyRun_InteractiveOneFlags()
// * PyRun_InteractiveOne()
