I am trying to build a path out of variables. I am reading lines from a file with a while loop. I then parse the information into variables. Here is my code 


my ($var1) = 'stuff_to_cut_out_with_substr_FOO';
my ($var2) = 'stuff_to_cut_out_with_substr_BAR';
my ($var3) = 'stuff_to_cut_out_with_substr_LOST';

if (/foo/) {
$var1 = substr($_, 8);
} elsif (/bar/) {
$var2 = substr($_, 7);
} elsif (/lost/) {
$var3 = substr($_, 5);
}

my ($path) = $var1 . '/' . $var2 . '/' / $var3
say "$path";

The problem is var1 is being replaced in the $path variable. The output looks like "obar/lost" instead of "/foo/bar/lost". When I print just the variables $var1, $var2, and $var3 they have the correct data in them. The problem happens when I try to build them into a string. I've also tried the following code 


use File::Spec::Functions;
my ($path) = catfile($var1, $var2, $var3);

This second code results in the same output. It seems like some sort of pattern matching is going on but I can't figure this out to save my life.
