Experimenting is the best way to learn Rebol.

Uh, it seems to me you have discovered an unknown bug!
I do not think that less agressive evaluation should mean this.
BTW, the behaviour is very strange:
>> do :+ 1
** Script Error: ?op? expected value2 argument of type: number pair char money
date t
ime tuple
** Near: do :+ 1
This means that the + is evaluated and ask two args, but the return value is a
wrong op!, instead of an integer!
The same happens also if the op value is inside a block.
It sems to happen only with op! not with function/action values.
These op! are a real patch in Rebol.
You should send a message to RT feedback.
