Passing space contained values as option to perl

Space ignorance issue, when passing perl script with option(space contained value) as argument.

test.pl

use strict;
use Getopt::Long;

my $option;
GetOptions(
 "myreg=s"=>\$option,
);

print "Option: $option\n";

I have a shell script and when I pass the perl script with option (space contained value) the script print only the option value before to the space.

/my/test/script.sh /my/testing/test.pl --myreg='Reg 1'

The above execution prints,

Option: Reg

What the issue? Please assist.

It's because of improper escaping performed by /my/test/script.sh, something along the lines of doing $@ or exec $@ instead of "$@" or exec "$@".

$ cat ./bad
#!/bin/sh
exec $@

$ ./bad ./test --myreg='Reg 1'
Option: Reg

$ cat ./good
#!/bin/sh
exec "$@"

$ ./good ./test --myreg='Reg 1'
Option: Reg 1
