Where does that happen?  I'm pretty intimately familiar with the Template
Toolkit, having written the Python port, so I know that all method calls in
a template occur in scalar context, and so "b.cs" in a template should
indeed translate to "my $val =3D $b->cs;" on the Perl side.

There's talk of introducing a new operator in the next version of TT,
perhaps ".@", that would introduce list context to a method call, and do
something more like "my $val =3D [ $b->cs ];", but it's definitely not here
yet.

So after some finagling, my template now reads:

[% FOR a IN as; FOR b IN a.bs_rs; !b.cs_rs.defined; "<br>"; END; END %]

And this is the output:

1
1

Still seemingly not the right thing.
