And
$a = $something->{very}->[$complex] - $that('goes')->to(qw(the line end))
+ and_then('wrapped_like_this');
is two statements?
(and not even a "Useless use of a constant in a void context" warning)
Although I use this all the time, grovelling round the perl5 source, I could
only find this sort of idiom used in Match::BigInt's tests. And that was
like this:
plan tests => 669
+ 16; # own tests

There's nothing wrong with stealing, er "borrowing" the good bits of
reptiles though, is there?. I didn't think that perl was fussy about where
it gets its inspiration from. And they shouldn't complain, as imitation is
the sincerest form of flattery.

Hmm. So if some saboteur erases all end-of-phrase markers from the musical
score you are reading, does that mean that after a while you turn blue and
then fall over? :-)
