[LA.pm] Alias to a dynamically scoped variable?

[William Reardon]

Just wondering, is it possible to create an alias to a dynamically 
scoped variable?

E.g, such as in this case $foo & $bar both equal 20?

{
   my ($foo, $bar);
   *foo = *bar;

   $foo = 10;
   $bar = 20;

   print "foo: $foo\n";
   print "bar: $bar\n";
}

When run with warnings, it's clear that the aliasing is taking place 
on the global versions of foo, not my my guys.

(I've found a different way to do what I was trying, so at this 
point, it's just curiosity.)

Thanks!
