I think there is a solution that would let Dekel read his old docs while
enforcing nested braces (thanks to Andreas Matthias <[EMAIL PROTECTED]>
in de.comp.text.tex):
\newif\ifcomment
\commentfalse
\ifcomment
\def\makeamptab{\catcode`\&=4\relax}
\def\makeampletter{\catcode`\&=11\relax}
\def\b{\makeampletter\expandafter\makeamptab\bhelper}
\def\bhelper#1\e{}
\long\def\bi#1\e{}
\else
\def\b{}
\def\e{}
\fi
...
\[\begin{array}{ccc}
1 & 2\b & 3\\
4 & 5\e & 6\\
7 & 8 & 9
\end{array}\]
If one puts the definition of \b and \e in the preamble, the math parser
reads \b and \e as "unknown makros without arguments", puts non-intrusive
'b' and 'e' in red there _and_ everything is rendered "correctly"...
This would mean I could insist on properly nested braces in a cell.
Is that acceptable to everone?
