commit de85ae9eccb84284873d419c899743a85bd4e66a
Author: Peter Selinger <selinger at mathstat.dal.ca>
Date:   Fri Jul 4 10:31:20 2014 -0300

    Added fixity declarations for member, notMember, union, and intersection.
    
    Milan Straka: It is quite unlikely that this ever gets merged, as it can
    cause build failures (it broke the testing suite for example) and offers
    in my opinion little benefit.
