Flush fact cache from within playbook?

Hi

I'm using fact caching which works great.
For a specific task in one of my playbooks I don't want to use cached
facts but "fresh" ones.
I'm aware of the --flush-cache command line option, but the playbook
in question can be included in others, so it's not always clear when
running the main playbook if the cache should be flushed. To be safe I
could just always use --flush-cache but that defeats the purpose of
cached facts.

Is there a way to flush the cache from a playbook?
Or any other suggestions for doing this (or maybe workarounds).

Thanks

http://docs.ansible.com/ansible/meta_module.html has a 'clear_facts' .

Spot on, thanks!!
