This feature has been added in r4366 (it really means we no longer
check for "over" correlation):
t = table('t', column('a'), column('b'))
s = select([t.c.a]).where(t.c.a==1).correlate(t).as_scalar()
s2 = select([t.c.a, s])
self.assert_compile(s2, """SELECT t.a, (SELECT t.a WHERE t.a
= :t_a_1) AS anon_1 FROM t""")
