That strikes me as irrational. When handed an inexact number, Scheme
procedures do their best: they return 4.0 as the sum of 2.0 and 2.0,
and #t as the value of the integral property of 4.0.

Original line from The Warrior's Apprentice by Lois McMaster Bujold:
"Only on Barrayar would pulling a loaded needler start a stampede toward one."
English-to-Russian-to-English mangling thereof: "Only on Barrayar you risk to
lose support instead of finding it when you threat with the charged weapon."
