3.
myWorld3: context [
helloWorld: none
set 'helloWorld func [][print "Hello World"]
]
>> probe myWorld3
make object! [
helloWorld: func [][print "Hello World"]
]

No. Evaluation of 'func creates a function! value. 'set takes the second
value and assigns that value as the value of the first value (a word!
value). Rebol looks for a matching word in the "closest" enclosing context.
If none is found, Rebol creates a word in the global context.
