Comment:
I've posted a first draft of a patch to make use of weakrefs optional (did
not add doc, nor changed the test added or modified by Simon yet).
I've surely forgotten some places where action are defined etc.
After doing that, I've begun thinking that Simon is right and that Actions
are too much related to the coecion system for this approch to be valid.
Maybe using weakrefs all the time, even though objects can become unusable
is good enough.
