Hi there! I have "ported" all of srfi-151 to guile. There wasn't that much porting involved, since most of the functionality is provided by guile as srfi-60 and the basic bitwise arithmetic in guiles standard environment.
It passes all the tests in the srfi document. If one wants to include it in guile's main distribution (as FSF-copyrighted LPGL), you would need to make a clean-room implementation of the procedures in bitwise-other.scm (bits->vector, vector->bits, bit-swap, bitwise-fold, bitwise-for-each, bitwise-unfold and make-bitwise-generator). I don't know about the tests, so probably them as well. The rest of the code is public domain (code by Olin Shivers edited by John Cowan, and code by me). The repo is here: https://bitbucket.org/bjoli/guile-srfi-151/ and the srfi document can be found here: https://srfi.schemers.org/srfi-151/srfi-151.html Best regards Linus Björnstam
