"Would you convey my compliments to the purist who reads your proofs and tell him or her that I write in a sort of broken-down patois which is something like the way a Swiss waiter talks, and that when I split an
infinitive, d*** it, I split it so that it will stay split."
- Raymond Chandler, to the editor of the Atlantic Monthly, 1947
