I am running the script below in Strawberry Perl 5.24.1 on Windows 10. When quotes are added to a filename in a scalar variable, open fails with error message "Invalid argument". The docs for open did not shed any light on this issue.

It doesn't seem right that the presence of quotes surrounding a filename in a scalar variable should cause open to fail. When the line in the script that adds the surrounding quotes is commented out, open works fine.

Your thoughts? 

#!/usr/bin/perl
use strict;
use warnings;
my $temp_file = $ENV{'APPDATA'} . '\test.tmp';
$temp_file = '"' . $temp_file . '"';
print "|$temp_file|\n";
open(my $fh, '>', $temp_file) or die "Error opening $temp_file $!\n";
