Rename the STRUCT: point word to something else because it conflicts with other unit tests which define a point word in scratchpad. The struct point is redefined to a tuple point and causes the macro-expansion to error out now that structs are properly reset, so instead we just give it a unique name so it doesnt get redefined. Perhaps examples should define their own vocabularies instead of using scratchpad.
