Browsing through the standard Perl modules, I came across this little number. Considering how much we push strict and warnings, wouldn't it be a good idea to add this module to the list? Eg, if you ever post example code at the monastry like this:
open(FILE,'/path/to/file');
print while (<FILE>);
close(FILE);
...
open(FILE2,'/path/to/file2');
print while (<FILE2>);
close(FILE2);
Someone will always add, "Always use strict, warnings and check whether the files opened OK".
#!/usr/bin/perl -w
use strict;
open(FILE,'/path/to/file') || die $!;
print while (<FILE>);
close(FILE);
...
open(FILE2,'/path/to/file2') || die $!;
print while (<FILE2>);
close(FILE2);
Wouldn't it be good practice to suggest adding 'use Fatal;' in as an option instead? ie
#!/usr/bin/perl -w
use strict;
use Fatal qw(open close);
open(FILE,'/path/to/file');
print while (<FILE>);
close(FILE);
...
open(FILE2,'/path/to/file2');
print while (<FILE2>);
close(FILE2);
It just looks cleaner to me. A quick SuperSearch doesn't bring up any previous discussions on this, so I just wondered if there's any reason why this little module appears to be rarely used/discussed?
Thoughts anyone?
