"break" inside iterate_outward{} doesn't work. Maybe not surprising
since the macro uses a for() loop inside a while() loop. Sometimes
"break" has the effect of a "continue", and that took a deliberate
effort to detect. This can easily become hard to find bugs for the
unwary.

If "goto" is perfectly valid C, less ambigous and equally well
defined as "break", then what exactly are the reasons for
discouraging it's use?
