No matter what virtues your technique has or lacks, this particular
line is surely broken; it will never die, even if the file can't be
opened. Check the table of precedence in the perlop manpage. Cheers!
Wow, lots of words; no help.
Things that are not in the documentation:
open my $omarfile, '<', "junk" or die "input file \"junk\" cannot be opened;
$!";
Note the use of the lexical, 'my $omarfile', file handler.
Note the use of the tri-argument open.
Note the use of 'or die'.
(Note the correct spelling.)
Reading documentation is good; but it out of date with respect to best
practices. Reading `perldoc perlop` will not correct the errors in the
statement. Reading `perldoc -f open` will tell you what's possible but not
what's the best practice.
