set returning functions.

Hi all,

How can one make a set-returning function behave like
generate_series(). If I cobble up an srf with plpgsql i have to do
select * from mysrf().
But i can do select generate_series(1,10) or select this,  that,the
other,generate_series(1,5) from sometable. Essentially I would like to
be able to have my srf behave like that.
