- Sidenote: I refuse to call object behavior "reference by
default",
I've had too many people notice that it's not actually true
Hear, hear. My favourite terminology here (and I'm sure it
was in the original description, when the change was first
proposed, but got lost along the way) is to say that objects
are always represented by their handle. Then variables
contain the handle, and you can have copies of the handle
and references to the handle which now behave exactly as
expected. I've produced a couple of major lightbulb moments
in people with this explanation, but it all stems from
introducing the concept of an object's handle rather than
saying objects are reference by default.
Please consider promoting this terminolgy to general use --
it would make it so much easier to explain certain
behaviours which currently have high WTF factors.
Cheers!

i usually got these "aha!" events when using inodes
and hard links as metaphers ...
