- * These exception-handling macros are split up to

- * exception object; typically it will be or contain an integer,
- * because Perl's internals use integers to track exception types:

- * JMPENV_PUSH, but several of its constitutent macros, to arrange for
- * the Perl internals to call thrower() rather than longjmp() to
- * report exceptions:
- *
- * dJMPENV;
