Tabular versus Array

All,

We're experiencing problems with people using

\begin{tabular}.... \end{tabular}

in the wrong way.

In theory tabular should only be used in text, not in mathematics, though our implementation of LaTeX is reasonably forgiving.

Last night we put the tabular into what we call 'strict' mode. Therefore any equation containing this command will need to be grammatically perfect, otherwise we reject the whole thing.

This though may leave people with legacy equations that now fail, though if they're being used frequently our caching system will keep them.

On reflection we're now thinking of simply replacing

\begin{tabular}.... \end{tabular}

with

\begin{array}.... \end{array}

Does anyone anticipate any problems with this?
