Hi Louis,

kkkkk is a word, and REBOL is evaluating it to find the value it references,
to see if it is an email! value. If you give it an email value, the scanner
will recognize it as such.
>> e: [gregg--pointy--com]
== [gregg--pointy--com]
>> email? e
== true
>> email? [gregg--pointy--com]
== true
HTH!
