The other examples in the ticket play out the same way:

I encountered the coverage problem inherent in this code in the
constructor of a module whose maintenance I recently assumed. (For that
matter, I could have encountered it in modules I myself wrote and still
maintain.) I eventually figured that there was no reasonable way to
make the "red" in the top line of the condition box go away. And since
that was the last remaining bit of uncovered code within the
constructor, I figured I should clean that up as well. So I re-coded
along these lines:
my $self = ref($class) ? bless( {}, ref($class) )
: bless( {}, $class );
More verbose. Less elegant. But more strictly precise. And 100%
testable with reasonable conditions.
