'delete' keyword

[%u]

Sorry for the second email, but another idea I forgot to mention is this:

Instead of logging (or even with logging!), allow a debug feature where the
'delete' keyword would walk all of the memory and check for references to the
object before actually deleting it, and if there's a problem, just have it do an
assert(0). This will make debugging a breeze, and it would pretty much clear up
any problems with safety and all.

Does that sound like a good (and reasonably simple) option?

Thank you!
