Globjects

• Before we see remember and gobackto, here's some syntax

• You can use a glob as if it were a reference to any sort of thing.

• For example:

        $N = 119;
        $v = ${*N};
        $r = \${*N};

• $v now contains 119

• $r now refers to $N so that $$r is 119.

• In particular, if *g is a glob, %*g is its hash

  • *g->{key} looks up key in the hash

• If $gr is a globref, *$gr is the glob

  • %*$gr is the glob's hash

  • *$gr->{key} looks up key in the hash
