This is beginning to sound like Test::More.
use Test::More tests => 42;
...
or
use Test::More;
...
done_testing;
So maybe follow that kind of pattern. But I am still lost why
typing "use feature 'yield_true';" is better than "1;".
Looking back at the pre-RFC itself, I don't think the "motivation"
is sufficiently, developed.
"Eliminate the need for a true value at the end of a Perl file."
Okay, but why?
