Dear Monks,
I wanted my code to be able to accept the input flexibly, either from PIPE: 
$ perl othercode.pl | perl thiscode.pl

[download]
or from STDIN 
$ perl thiscode.pl SOMEFILE.txt

[download]
Currently I have this construct. But is there a better way to do it? 
#!/usr/bin/perl -w
use strict;

# thiscode.pl

my $file = $ARGV[0];
my @lines;

if($file)
 {@lines = `cat $file`;}
 else
 {@lines = <STDIN>;}  # Update: Also, can I do better than 'slurping' 
+here?

foreach (@lines) {
  #Do my stuff here
}

Regards,
Edward
