Here's a misleading lack of an error message:
(defn foo [x]
{:pre (odd? x)}
x)
The code may look fine at a glance, but the precondition is not
wrapped in a seq, so the actual preconditions become checks for
truthiness of `odd?` and `x`.
Maybe precondition forms should be required to be vectors, so that
function call forms can't be mistaken for lists of preconditions?
