[Python-ideas] Break multiple loop levels

[David Mertz]

I don't love the 'break break' syntax idea. But I find myself wanting to
break out of nested loops quite often. Very rarely could this be
transformed to an 'itertools.permutation' de-nesting, albeit perhaps more
often than I actually do that.

My usual kludge is a sentinel 'break_outer' variable that gets set back and
forth between True and False working the loops. Usually work a name that
descriptive of the actual domain of the code.
