The `rationalize` algorithm is by Alan Bawden and Marc Feeley.

Lars T Hansen wrote SRFI-11 (let-values, let*-values macros).

Olin Shivers wrote the SRFI-1 list-processing library, and the SRFI-13 reference impementation.

John David Stone wrote SRFI-8 (receive macro)

Jussi Piitulainen wrote the SRFI-25 specification and tests.

Richard Kelsey and Michael Sperber wrote SRFI-34.

Anthony Carrico wrote the SRFI-37 reference implementation.

Panu Kalliokoski wrote the SRFI-69 reference implementation.

Donovan Kolbly wrote the srfi-64 “meta” testsuite. Alex Shinn improved SRFI-64 portability.

Philip L. Bewig wrote the SRFI-41 (streams) specification and reference implementation.
