Recently, a user reported that the bigip_facts module was failing with the error
received exception: object of type 'itertools.imap' has no len()
This reported was occurring at line 1657 of the bigip_facts module
bug report is here
https://github.com/F5Networks/f5-ansible/issues/25
Upon further investigation, the map function for returning the specified
includes was returning an iterator, and calling len() on an iterator does
not work.
I believe this problem was caused by part of the Python 3.x effort insofar
as the inclusion of this line
https://github.com/ansible/ansible/blob/devel/lib/ansible/module_utils/basic.py#L143
seems to affect our usage of map(), probably for the better anyway, and we need
to change our expectations in our module's code to no longer assume a list, but
instead assume an iterator.
After trawling through the module_utils/basic code, I think a list
comprehension is more appropriate here anyway, so I'm changing it to be
that. The affected user reported it works this way, and my own testing
on 2.2.0 supports that.
