Hello, I think I found a bug in (srfi srfi-64) module shipped with GNU Guile.
The specification says that test-eqv is equivalent to: > (test-assert [test-name] (eqv? expected test-expr)) Hence the test-assert's requirement to evaluate test-name only once applies. However the test-name is evaluated multiple times: (use-modules (srfi srfi-64)) (test-begin "x") (test-eqv (pk "t") #t #t) Leading to: ;;; ("t") ;;; ("t") Have a nice day Tomas Volf
