A typo after rafactoring the function into 3. Thanks.

I have no idea. It is used in Perl library Test::Reporter, so I trust it
is necessary for MAC OSX.

In Perl, the last statement's result is the returned value from a
function. Compare:

    $ perl -e 'print  if $_ = do{ 1; }'
    1

Yes, it's a style issue. I don't personally use "return" at the end of
simple functions in Perl.

I'll add the "return".
