Test #1: should all be verbatim

\setlength\unitlength{10pt}
\begin{picture}(12,10)(-2,0)
%\linethickness{0.4pt}
\qbezier(2,6)(7,6)(9,3)
\qbezier(2,0)(7,0)(9,3)
\qbezier(2,6)(4,3)(2,0)
\qbezier(1,6)(3,3)(1,0)
\put(9.75,3.00){\circle{1.50}}
\put(10.5,3.00){\line(1,0){1.50}}
\put(0,5){\line(1,0){1.5}}
\put(0,1){\line(1,0){1.50}}
\end{picture}


Test #2:

This form is *not* handled:

\newcommand\topfraction{.7}
\newcommand\bottomfraction{.3}
\topfraction\over\bottomfraction

But it is handled if it looks like this:

%
%
.7 divided by .3
.7/.3
.7\over.3


Test #3: simple parameterless expansion 

  The formula for water is H$_2$O. 
  H$_2$O\ is the formula for water.


Test #4: with arguments, and multi-line...

How about \(x_1 ... x_n\), or \ensuremath{y_1 ... y_n}?


Test #5:

Day 3 is %
\ifthenelse{\equal{3}{1}}{Monday}{}%
\ifthenelse{\equal{3}{2}}{Tuesday}{}%
\ifthenelse{\equal{3}{3}}{Wednesday}{}%
\ifthenelse{\equal{3}{4}}{Thursday}{}%
\ifthenelse{\equal{3}{5}}{Friday}{}%
\ifthenelse{\equal{3}{6}}{Saturday}{}%
\ifthenelse{\equal{3}{7}}{Sunday}{}%
!

Test #6: nested expansion:

These should be in order: A B{}CDE

These should be in order: \leta+\#B{}CDE
