[REBOL] Re: A few questions about words

Hi Eric,

look at the following console session:

    >> word1: "initial value"
    == "initial value"
    >> set 'word1 "new value"
    == "new value"
    >> word1
    == "new value"
    >> word2: 'word1
    == word1
    >> set word2 "even newer value"
    == "even newer value"
    >> word1
    == "even newer value"

The above makes use of the fact that SET expects a LIT-WORD! to determine
which word it should assign the value to.

You're not ;-)

Look at

    >> f1: func ['word] [print ["Function was called on word" word]]
    >> ;         ^^^^^
    >> f1 some-word
    Function was called on word some-word
    >> f1 'some-word
    Function was called on word some-word

    >> f2: func [word] [print ["Function was called on" word]]
    >> ;         ^^^^
    >> f2 some-word
    ** Script Error: some-word has no value.
    ** Where: f2 some-word
    >> f2 'some-word
    Function was called on word some-word
