simpler method possible, that distinguishes thanbles from within.

This line has an equivalent method that I think should be one method. if we check if the data is a then-able object
and branch execution from there

graphql-relay-py/graphql_relay/connection/arrayconnection.py

Line 7 in 17ce2ef

def connection_from_list(data, args=None, **kwargs):

graphql-relay-py/graphql_relay/connection/arrayconnection.py

Line 24 in 17ce2ef

def connection_from_promised_list(data_promise, args=None, **kwargs):

Im thinking something like this

if is_thenable(data):
     return Promise.resolve(data).then(
         lambda data: data, len(data)).then(
             lambda data, _len: connection_from_list_slice(
                 data,
                 args,
                 slice_start=0,
                 list_length=_len,
                 list_slice_length=_len,
                 **kwargs))
_len = len(data)
return connection_from_list_slice(
        data,
        args,
        slice_start=0,
        list_length=_len,
        list_slice_length=_len,
        **kwargs
    )

Let me know if there is a specific reason, why there are two methods
