These points seem to be contradictory:

| Inexact infinities and NaNs are now assumed to exist. In the
| previous draft, their existence was not always assumed, yet was
| sometimes assumed implicitly.

| Although implementations of Scheme are not required to represent
| infinities and NaNs

Examples for div0 and mod0 lack the 0 subscript.

The whole SRFI is long and has redundant fragments, for example the
table of atan branch cuts is written 3 times.
