Cormac McCarthy is interviewed on his use of punctuation:
I believe in periods and capitals, and the occasional comma and that's it. Or you can use a... colon if you're getting ready to give a list of something that follows from what you just said.
I was tempted to put a semicolon after 'that's it', but decided it would go against the spirit of what he was saying. No discontinuities 'greater than that indicated by a comma but less than that indicated by a full stop' for Cormac.
