What I had my mind is that the author just concentrates on writing out the text logically (just as in the case of the quotes); this then provides the context which a style can process. Thus, one would simply write \begin{equation} 2+2=4 \end{equation}. % Note period here ^ The \end{equation} makes an one character lookahead, and processes it according to the style definition. (I think this would be possible with the "environments with hooks" I wrote some code for a long time ago.)
