[REBOL] Bug? 'func not really 'func Re:

COPY isn't evaluating the words in the block. The values in the "opt type" subblocks of THIRD :FUNC are datatypes:
>> type? probe first fourth third :func
block! == datatype! whereas FUNC usually needs words in those subblocks. If you don't have a word there, the contents of those subblocks are treated as samples of the datatype:
>> cube: func [x [2 2.1]][x ** 3] >> source cube
cube: func [x [integer! decimal!]][x ** 3] LOAD MOLD, Ladislav's solution, converts the datatypes back to words. Hope this makes some sense ... Eric
