	It is used enough to make it into the Collins Cobuild dictionary,
which uses statistics on word occurrences to decide whether they
should be included. One of the examples they regard as typical is:
“I don't think you've change an iota”, which means more or less
“|new - old| < iota”, so it is not that far fetched.
