Hmm, probably well known but ... I have not met any direct warning of
this problem so far.
our %SOME_CONFIG = (
a => 1,
b => 2,
c => 3,
);
...
while (my($k,$v) = each %SOME_CONFIG) {
if( ... ) {
return; # or last, or throw exception
}
}
You probably see the problem - when this code is re-executed (next
request), the loop iterates just over 'the rest' of the hash.
Does there exist some way to protect before this problem (some kind of
auto-destructor, finally, whatever which would automatically rewind
the hash internal iterator while leaving the context)?
