Others have well dealt to this.

You're partially correct, in that more things will be becoming OO.
I'm picking that the old special variables and select() were harder to
grok than the new filehandle OO doodads will be.

Once again, partially correct but with some FUD.  RFC 9 wasn't
accepted in full.  %foo, @foo, and $foo are not the same thing.  What
was taken was

  $ref = %foo;

makes $ref hold a hash reference.  If you're a beginner and don't know
about references, don't do that.  It makes reference stuff more
convenient for those who know how to do it, and also simplifies some
of the wackier prototyping.  This is hardly "if you don't understand
references, you won't be able to use variables".
