Can you define empty? You mean not in the context?

Yes - there is a wrapper. I remember that there was a side effect of
this, but I thought that behavior was preserved. I will investigate.

Yes - by default, the first macro defined is permanent. There are
plenty of options to change the behavior to suit your need. In this
case...
velocimacro.permissions.allow.inline.to.replace.global = true
will fix it.

Well, reading the manual in the case of the macro persistance might have
given you a clue. I have been wanting to write something more
substantial about the VMs, so I guess this motivates me to do it.

No. The VM code has been very stable - the only change recently had to
do with 'local scope' namespaces, totally unrelated to this.

Why didn't you just ask?
