The problem is, that TO WORD! or MAKE WORD! can create some "artificial"
words that the Rebol parser normally recognizes as different datatypes. We
may consider that to be an "advantage" or a "disadvantage", but RT can claim
it to be a feature, not a bug.

Hmm, i didn't check it, but it really differs from:
word1: 'word1
word2: use [word2] ['word2]
and I don't know why.
