The recommended usage of open is:
open my $omarfh, '<', 'junk' or die "Input file 'junk' cannot be
opened: $!";
The three argument is preferred as a malicious user could enter a file
name that starts with '>'
The lexically scoped file handler is preferred since it won't interfere
with other file handlers.
Sure, I agree Shawn, but I also think it's nice to change the OP's code
as little as possible to turn it into something that works as well as
possible.
Plus most of the published literature still uses bareword filehandles
and offering something different unnecessarily complicates things for
beginners.
And there is no way that line of code could be compromised so the mode
parameter is unnecessary.
