Hmmm, perhaps you don't want to know what *I* was doing in 1987 :)

Anyway, if the LaTeX team is serious about preventing backwards 
compatibility problems, then we should do things like rename LuaTeX 
primitives into a "namespace" such that older documents won't be 
affected (within reasonable expectations of what naming schemes are 
being used in the wild).

I could imagine a future LaTeX configuration file doing something like 
the following to ensure that documents written for legacy versions of 
LaTeX still compile without problems.

   \let\formatname\luatex at formatname\let\formatname\@undefined
