% an idea by Herbert Voß (http://tex.stackexchange.com/a/7183/5049):
%   make the test character an (hopefully extremely) unlikely % with
%   catcode!=14;  let's make & a temporary comment char
%   save both catcodes just in case someone changed the defaults:
\edef\@elements@tmpa{
  \catcode`\noexpand\%=\the\catcode`\%
  \catcode`\noexpand\&=\the\catcode`\&
}
\catcode`\%=3
\catcode`\&=14
& the test:

    \expandafter\@firstoftwo
