Thanks for the comments. I'll grant that the desired operation of
link is somewhat ill-conceived. And I'll probably change it. But once I discovered the contextual issues, I couldn't just let them go. Perhaps the most readable approach would be to add a
size routine:
my $n = size($obj->link('next'));
sub size {scalar @_}
The routine doesn't do a thing except force a list context on
link and scalarize its return value. But having it there also makes clear what's intended.
<heretical rant>
In my mind size ought to have been a built-in function, rather than relying solely on implied semantics and contextual hocus-pocus to do its job. The number of newbies who try to use length for this purpose is, by itself, testament to an unmet need.

And just think of all the questions in SoPW that might've been eliminated!
