FILE-ERROR? Marc Nieper-WiÃkirchen 28 Apr 2020 15:19 UTC
Custom ports should be able to raise an error that fulfills
FILE-ERROR? of the R7RS.
R7RS itself does not define a procedure that allows one to forge such
an object (apart from hacks like intentionally letting OPEN-INPUT-FILE
fail), so such a procedure should be added to this SRFI.
