EDIT: Oh, I'm an idiot... for got to change:
$line .= $fh_iterator while $line =~ m{\\$};
To:
$line .= $fh->getline while $line =~ m{\\$};
However, the code does return the error below on the last line of my test file...
Use of uninitialized value $line in pattern match (m//) at parser3.pl
+line 17, <GEN0> line 5.

Hmm... well, I get a new error at least:/p>
Use of uninitialized value $line in pattern match (m//) at parser3.pl
+line 17, <GEN0> line 5.
Here's the accompanying code and test file:
#/usr/bin/perl
use strict;
use warnings;
use IO::File;
use 5.010;
my $filename = shift @ARGV;
my $fh = IO::File->new($filename, 'r');
sub fh_iterator {
my $fh = shift;
my $line = $fh->getline;
$line .= fh_iterator($fh) while $line =~ m{\\$};
}
while (my $line = fh_iterator $fh ) {
print $line;
}
