No type change here. [o1 o2] is just a block of words. In a block,
they are just words, though they are bound to the context they are
generated in. The two main options you have are:
>> foreach obj reduce s [probe obj]
>> foreach word s [probe get/any :word]
Note: you don't need to use a get-word! in the second example - in
some cases, the intent is clearer.
