Hi Christian,
the reason you get this behavior is that the words in the block,
[integer! string!], are not bound to the REBOL global context. Simply
say
b: reduce [integer! string!]
and that will do the trick. When you reduce the block REBOL binds the
words to the global context and now integer! = first b == true, and
string! = second b == true as well.
Hope this helps,
Elan
