Have a look at the m4 macro processor
changequote({,})dnl
define({func_body},{$$begin
raise exception 'I barfed on line #__line__';
end$$})dnl
create function some_func()
returns whatever
as func_body
language plpgsql;
This can be useful sometimes... but may ADD to your debugging
headaches if not used artfully!
