in thread Perl 6: Static/Dynamic Strong/Weak Type Systems

That just means it doesn't distinguish between types you feel are important. Strong vs. Weak typing has to do with how easy it is to coerce various types into one another. There are very specific types in Perl.

While you may be able to extract a scalar from an array and an array has a meaning within scalar context, that doesn't mean you can coerce the array into the scalar. Try doing any sort of meaningful work converting between formats and subroutines.

My criteria for good software:
  1. Does it work?
  2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?

    there is a hole: 
    use Devel::Peek;
$foo = *foo;
Dump($foo);

      Fair enough. For those who don't follow, the "hole" is that whenever an explicit glob is the RHS of an assignment, the member of the glob matching the LHS will be substituted. This is because a glob is both a type and a collection of types.

        no, no, what I wanted to show is that when a glob ia assigned to a scalar, the scalar becomes a glob!

        After 

        $foo = *foo

        [download]
        $foo is a glob!
