Waitasecond. Assuming you did not intend to say that the legs have some eyes, you want the $body->legs(...) to return the modified $body, right? So the $body->eyes will return the $body as well, right? So the $body->eyes->color returns the color of the body, not the color of the eyes, right? I guess not...

So what does the $body->method(...) return? The modified $body or some inner object? Or sometimes one and sometimes the other?

Method chaining works OK on objects that do not have any inner objects and whose method names make it very very clear which ones modify the object (and then return the modified $self) and which ones return some properties. As soon as it's not entirely clear, you're gonna run into problems.

Maybe it would be better to use somethign like this instead:

for ($body) {
  $_->legs(size=>42);
  $_->eyes(color => 'blue');
  print $_->eyes->color;
}

It's kinda shame you can't use something like

for ($body) {
  -->legs(size=>42);
  -->eyes(color => 'blue');
  print -->eyes->color;
}
