[Paul D. Anderson]

I think this is a great idea and a good example of adding to the 
library rather than changing the syntax.

"Wouldn't the sentence 'I want to put a hyphen between the words 
Fish and And and And and Chips in my Fish-And-Chips sign' have 
been clearer if quotation marks had been placed before Fish, and 
between Fish and and, and and and And, and And and and, and and 
and And, and And and and, and and and Chips, as well as after 
Chips?" — Martin Gardner
