And also
*{$x}{CODE}->() hi again
Interesting that assigning to *{$x}{CODE} is not allowed.
*{$x}{CODE} = sub { print "hi" }; Can't modify glob elem in scalar assignment...

    If I recall correctly--which i quite possibly don't--there is a proper syntax for doing that.

    But, like many people I suspect, I went through the process of playing with globs many moons ago, trying all the different forms and syntaxes, and then promptly forgot most of them because the are so few occasions when they are useful.

    It's one of those dark corners of Perl that's good to know it exists for the rare occasions that a use for it pops up. But when (if) it does, I have to go off and look up the syntax.
