Thanks, Holger!
Do I have the following essentially correct?
>> probe end!
** Script Error: end! has no value
** Where: halt-view
** Near: probe end! ;rebol has not "seen" this word in the global context
>> probe first first rebol/words
end! ;rebol has seen this word before, in 'rebol/words
== end!
>> undefined? first first rebol/words
== true ;'end! is not in the global context
>> undefined? in rebol/words 'end!
== false ;'end! is in the context of 'rebol/words
>> value? first first rebol/words
== false ;'end! does not have a value in the global context
>> value? in rebol/words 'end!
== false ;'end! does not have a value in the context of 'rebol/words
