To be a bit more precise: The quotation is part of the code of the 
surrounding colon definition.  A word can return a quotation which is alive 
"forever" (i.e. until you forget the word or execute a marker).  So things 
like "access to locals within the surrounding word" is better avoided - this 
would only work reliable when you had implemented real closures; and while 
that certainly is possible, it is IMHO not desireable for Forth (too 
complicated).
