in thread do/redo or for(;;): what's Kosher?'s not obvious to me that it's an infinite loop...

Its easy to see on a short, simple loop, but on longer more complex things I just label loops as such (or whatever they function as):

# I usually include the label in the loop control statement # so everything's immediately obvious, but I omit them here. LOOP: { last if $something; ... redo; } INFINITELOOP: { ... redo; } FILTER_FOO_LOOP: { next if foo(); ... redo; } FOO_SWITCH: { foo() and last; foobar() and last if something(); }
