Transfer indirect params via chain of fixtures

[Tusenka]

I invoke
`
@fixture(scope="function")
def a(b):
yield b()

@fixture
def b(request):
yield lambda: request.param

@mark.parametrize('param', ["a"], indirect=True)
def test_a(a, param):
assert a==param
`
Got
'SubRequest' object has no attribute 'param'

How to transfer param from test_a to the b(throw a)?

That's not supported at the moment

Parameters only ever go to the fixture they belong to
