 Subject: Re: c++/7016: missing definitions for <?= and >?=
 
 The original issue was not (only) with overloading, but also with this
 operator not being available for the basic scalar types (while <? and >?
 are). Thanks, Jan

 State-Changed-Why:
     This is probably a corner case whether I should close the
     report: this has never worked (used to ICE)
     ---------------------------------
     class C {};
     C operator <?= (C) { return C(); }
     --------------------------------------
     I don't think it was ever documented that one should be
     able to overload this operator (a gcc extension anyway).
     Now we at least get a reasonable error:
     g/a> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c x.cc
     x.cc:2: error: expected identifier
     x.cc:2: error: expected type-name
     x.cc:2: error: expected `,' or `;'
     
     So the fact that the new parser rejects the code is ok, and
     is not removing a documented extension.
