Hello,

I think I found a bug in (srfi srfi-64) module shipped with GNU Guile.

The test-group is defined as equivalent to:

    (if (not (test-to-skip% suite-name))
      (dynamic-wind
        (lambda () (test-begin suite-name))
        (lambda () decl-or-expr ...)
        (lambda () (test-end suite-name))))

`test-to-skip%' is not defined anywhere (great), however in the text we have
this sentence:

> However, the entire group is skipped if it matched an active test-skip

Since active skip list is mandated to be a property of test runner, in case the
test runner does not exist yet, there cannot be active skip list.  Hence the
group should run.  However:

    (use-modules (srfi srfi-64))
    (test-group "x"
      #t)

Leads to:

    Backtrace:
