TypeError: 'function' object is not iterable

Hi,

The following code works fine before 1.11.0

@funcy.retry(5, lambda attempt: attempt * 2)

Now it's broken with the following exception

File "/Users/ykoasanto/Veracode/Agora/Laputa/agora-ecsinfra/ecsinfra/service/deploy_helpers.py", line 196, in poll_ecs_for_steady_state kankyo_name, service_name) File "/Users/ykoasanto/Veracode/venv/ecsinfra/lib/python2.7/site-packages/funcy/decorators.py", line 38, in wrapper return deco(call, *dargs, **dkwargs) File "/Users/ykoasanto/Veracode/venv/ecsinfra/lib/python2.7/site-packages/funcy/flow.py", line 93, in retry errors = _ensure_exceptable(errors) File "/Users/ykoasanto/Veracode/venv/ecsinfra/lib/python2.7/site-packages/funcy/flow.py", line 122, in _ensure_exceptable return errors if is_exception else tuple(errors) TypeError: 'function' object is not iterable

I think the removal of the check for a list type here have caused this issue:

The second argument is errors and this never worked. It failed later though:

In [1]: from funcy import retry, raiser

In [2]: f = retry(5, lambda x: 1)(lambda: 10)

In [3]: f()
Out[3]: 10

In [4]: f = retry(5, lambda x: 1)(raiser())

In [5]: f()

You should name argument here:

@funcy.retry(5, timeout=lambda attempt: attempt * 2)
def func(...):
    # ...
