This can easilly be done with a comment:

// must fobnicate before we tweak
assert (x ? t(3) : 3434==i+j);

   And there was me thinking that the compiler ignored comments ;-)

   If you wish to do this 'properly' w/ assert:

     assert (("must fobnicate before we tweak", x ? t(3) : 3434==i+j));

   I think both of these help to reinforce points about usability and
   friendliness! Another point here being that library user and author are
   different roles, and there can be quite different requirements for what
   may superficially seem to be the same concept, ie debugging.
