There is a trick:
avoids (implicit) acquisition.
How it works:
"aq_explicit" returns the explicit acquisition wrapper
for "this". This wrapper does not acquire automatically
but must be told explicitly. As "hasattr" does not to
that, it tests for an attribute of "this()" and
not an acquired attribute.
