...And it does so by bypassing SCALAR_OPS entirely. Oops. It doesn't work
if the scalar vmethod is named something besides "field".
What you could do, though, is add a hash vmethod, assuming your object is
backed by a hash:
sub Foo::field { $_[1] }
$Template::Stash::HASH_OPS->{foo} = sub { shift->field(@_) };
Template->new->process(\"[% x.foo(42) %]", { x => bless({ }, 'Foo' });
