No - that's not correct. Joel says phone numbers are of the form
###-#### or ###-###-#### so phoning "123-123-234-2112-3444" would
give you a number-not-found error...

No, "whatisthis?" is not how you write sentences - words are supposed
to have spaces between them...

Well, 123-4567 could be a phone number or arithmatic too - though to
REBOL's mind it's an invalid date. But the rule is, if in doubt,
blot it out! (:
So, can you write text with phone numbers in of the form ###-#### or
###-###-#### that /won't/ be blotted out by that parsing rule? (Hint:
You can! :)
