If everyone followed this approach always, you wouldn't know that zero
is a valid number. For a long time it wasn't so. Any course in history
of mathematics mentions this. The same course most likely mentions Kuhn,
"normal science," groupthink, and other related stuff.

I'm starting to be really afraid of libm project. It involves some quite
fresh results from non-trivial mathematics, some of them were obtained
within recent 5 years.
