My question is this: wouldn't the mkdir on line 4 reset the $! value,
and also the %! hash if it failed? If so, the rest of the checks
would be looking at the result from mkdir's failure, not the failure
of the open, correct?
I think the answer is that in an if-elsif-else construct, Perl will
execute only the first block whose conditional is true and then jump to
the code that follows.
