in reply to Nested evals - are they evil?

Consider

eval { my ($dev, $inode) = stat($dir) or die "stat $dir\n"; eval { opendir D, $dir or die "opendir $dir\n"; eval { my $e = readdir(D) or die "readdir $dir\n"; eval { open my $in, '<' $e or die "open $e\n"; # etc etc } } } }

Especially if there was lots of other code intertwined within those blocks, when sprinkled with lots of conditionals on, and assignments to, $@, to confuse the unwary. Now that's what I would call evil nested evals.

Your puny evilness cannot hope to compare with this evilness (which is what I was expecting to find when I read the title of this node). Your code is naught but exception handling, which is not so much evil as merely vile :)

[talexb]: TStanley I'm flying to Vegas in two weeks time. After that flights leaving Vegas and Phoenix are late at night .. I've been hearing that it gets so hot that the air isn't dense enough for planes to take off. Weird. Guess you won't have that problem.
[Corion]: Yay, vacation time now - one week off work (but a Perl workshop in the middle ;)) )
[talexb]: TStanley I just realized that I was in your area for a convention back in April. We were at the high school for the weekend, the one with the long driveway. Nice spot.
[TStanley]: I am heading to Arlington, Virginia next week, then I get to spend an entire week at home. Looking forward to that as I will have spent 7 weeks on the road by the end of next week
