Hi Joel,

<< What if REBOL had a new word, e.g. GLOBAL-CONTEXT-FROZEN (and
I'm quite happy for suggestions for a better name!), that
controlled whether adding new words to the global context were
prohibited? >>

Given the discussion a short while ago about people wanting the ability to
extend *any* context easily, what if you could do the following:

        UNFREEZE context
        extend context
        FREEZE context

        FROZEN? context
        <can't extend it if frozen>

I don't how they might work, if it's feasible, or if it's even a good idea,
but it's a thought.
