this looks more likely:

defined?: either rebol/version >= 2.100.0 [
	func [
		{find all defined words in the given context}
		context [any-object!]
		/local words
	][
		words: words-of context
		remove-each word words [not value? word]
		words		
	]
][
	func [
		{find all defined words in the given context}
		context [object!]
		/local words	
	][
		words: bind first context context
		remove-each word words [not value? word]
		words
	]
]

Thanks

One year left from last Carl's blog entry in R3 blog. Sad anniversary.

Yes, indeed. We should concetrate upon what we have. And we have 
clones, plus existing RT's products, which are still useable, although 
we would like to see them progress further. If Carl does not return 
to R3 one day, nor does he release its sources, it was big 5+ years 
of wasted time imo ...

Not a waste ... it has provided the drive to produce derivatives

It also suppressed the production of derivatives at the time

To be fair, that is because it was good enough

yes, it is usable.

but its missing a few key things which prevent a few few of us from 
moving to it.

No, there was already a drive to produce derivatives, because it 
wasn't good enough, and it was killed
