Yeah, that is a bad practice called symbolic references left over from
before we had real references. Modern Perl code uses the strict
pragma to turn that nightmare into an error. The following code
produces the error
Can't use string ("foo") as an ARRAY ref while "strict refs" in use at
t.pl line 7.
#!/usr/bin/perl
use strict;
use warnings;
my $y = "foo";
foreach (@{$y}){
print "i'm doing something with $_ \n ";
}
