foo {
if(12){
$self->out( <<'EOTT' );

EOTT
}
$self->out( <<'EOTT' );
<bar foo=$self->varsubst($self->getvar('blah'));'' />
EOTT
$self->out( <<'EOTT' );
<lala>
EOTT
$self->out( <<'EOTT' );
...

</lala>
EOTT
}

You'll notice some errors, like foo=..., I need to fix the varsubst stuff, as well as the missing $self->out before the </lala> tag.
