Please pardon my ignorance, but if Anthony's VI4 work
is done, includes block closures and is faster than the
stock VM, why is there reluctance to take it as a whole?

I've read some of the messages related to this, and from
my point of view, a new bytecode set and stack contexts
are both great improvements and we should want them as
well.

Could anyone enlighten me about the concerns?  I understand
there are emotional reasons (i.e. too much change for comfort),
but I don't see any technical drawbacks.
