Yep. You can just do this:
[% person.something_really_complicated %]
The method will be called there and then. You don't need to pre-calculate
anything and it will only get called when used.

Should do. Perhaps you need something like:
[% FOREACH thingy = person.something_really_complicated %]
[% thingy.this %] and [% thingy.that %]
[% END %]
This is assuming that the method returns a list of things. If it returns
a list of hash refs (a typical case) then you can indeed leave the target
off and the hash contents will get IMPORTed into the current variable set.
[% FOREACH person.something_really_complicated %]
[% this %] and [% that %]
[% END %]
