There are symbolic refs, but you have to stay in the symbolic ref world. If you create ${'1_'} as a symbolic reference, you have to continue to refer to it symbolically only. Perl barfs if you try to use it as $1_ later on. Here's a working example, though:

{
    no strict 'refs';
    ${'1_'} = 100;
    print ${'1_'}, "\n";
}

If you go on to dump the %main:: hash you'll see the package global $1_ does exist. Perl's syntax just doesn't support it as anything but a symbolic ref, I think.
