hmmm.. I also be glad if someone can explain this issue well
>> Fred: Try ["hello"]
== "hello"
>> fred
== "hello"
>> Fred: Try [print "hello"]
hello
** Script Error: Fred needs a value
** Near: Fred: Try [print "hello"]
>>
>> ? try
USAGE:
TRY block
DESCRIPTION:

** Script Error: fred needs a value
** Near: fred: do [print "hello"]
>> fred: do ["hello"]
== "hello"
>>
Looks like REBOL is being very consistent.
So RebGurus, how do you interpret "returns its value" in this context?
Which Rebol statements have value?
