Hello, I think I found a bug in (srfi srfi-64) module shipped with GNU Guile.
The specification says the following regarding the test-apply: > If one or more specifiers are listed then only tests matching the specifiers > are executed. That implies that specifiers are optional and the following code should work: (use-modules (srfi srfi-64)) (test-apply (λ () #t)) However it does not: Backtrace: In ice-9/boot-9.scm: 1752:10 8 (with-exception-handler _ _ #:unwind? _ #:unwind-for-type _) In unknown file: 7 (apply-smob/0 #<thunk 7fdf6ecc4300>) In ice-9/boot-9.scm: 724:2 6 (call-with-prompt _ _ #<procedure default-prompt-handler (k proc)>) In ice-9/eval.scm: 619:8 5 (_ #(#(#<directory (guile-user) 7fdf6ecc7c80>))) In ice-9/boot-9.scm: 2836:4 4 (save-module-excursion _) 4388:12 3 (_) In srfi/srfi-64/testing.scm: 947:34 2 (test-apply #<procedure 7fdf63956108 at /home/wolf/src/guile-wolfsden/tests/s…>) 938:47 1 (test-apply #<procedure 7fdf63956108 at /home/wolf/src/guile-wolfsden/test…> . _) In unknown file: 0 (reverse #t) ERROR: In procedure reverse: In procedure reverse: Wrong type argument in position 1: #t Have a nice day Tomas Volf
