I just can not open some files I received.

When this simple chunk of code is executed 
use IO::File;
my @data;
if (-e $file) { print "\nopen $file\n"; }

if (my $fh->open("$file, r")) {
print "I'm in\n";
@data = <$fh>;
$fh->close;
}

something goes wrong. The file is found (message "open filename" is printed, with filename being the correct name of the file), but then I get this error from the I0::File package:

Can't call method "open" on an undefined value

In other words, it's like there is no string assigned to the variable $file!
