hi everyone

linuxer made the following reply on a previous post of mine. I have a lot of questions about it so I decided to make a separate post.

"Even in a short test script you should check if open was successful. Especially when writing to a file." 
my $output_file = 'hoser.txt';

# using three argument form and die if there's an error
open my $fh, '>', $output_file   or die "$output_file: open(w) failed:
+ $!";
my @file_info = stat $fh;        or die "$output_file: stat failed: $!
+";
close $fh                        or die "$output_file: close(w) failed

My question is ... why? Doesn't this take more work (ie for perl, longer runtime)? I suppose if you put an or, it'll simply skip over it if successful and cost nothing extra. Is this correct? Finally, is this good practice when developing code (error tracking) or do most include even in the final draft.
