Scheme 48 is a free software Scheme implementation using a bytecode interpreter.[2] It has a foreign function interface for calling functions from C[3] and comes with a regex library[4], and a POSIX interface.[5] It is supported by SLIB the portable Scheme library and is the basis for Scsh, the Scheme shell.[2]
It is called "Scheme 48" because the first version was written in 48 hours in August 1986.[6]
The authors now say it is intended to be understood in 48 hours.
