[mercury-users] using mercury for parsing/scanning

When using DCGs to scan character strings, is there an
alternative to this:

keyword -->

I'm hoping for some syntactic sugar - I'm too lazy to
type in all the quotes and commas every time.

Also, I'm currently reading input a word at a time and
then passing around the character strings.  Is it
better to do this or to read input straight from the
stream every time?  (My current solution involves some
pushback when the current word isn't all consumed.)  I
am just doing scanning, not parsing yet, so I never
need more than one word.
