But of course, if does the goto (to get the correct caller lexical scope),
then it's too late to print 'not ok' if the import fails (e.g. if it dies).

So I suspect that use_ok() is fundamentally unsuitable (and not fixable)
for modules that affect the callers lexical scope.

In which case, it's probably best to just document this limitation in
Test::More, and suggest to Semi-Semicolons's maintainer to avoid

If this is acceptable, then this ticket ceases to be a 5.14 blocker.
