Please, I was not arguing in favour of doing everything in terms of
"if" and "goto". I was
- pointing out that "break" is merely a short spelling of "goto break",
- and that it would be possible use the same mechanism to add the
constructions "continue", "resume" and "restart" to loops, although
spelling them "goto continue", "goto resume" and "goto restart",
- and begging for help in doing so from people that understand the
logic of lparser.c.
