Here is a fragment of a question:
A fly is closed in a cylindric container of radius $R=[%R%]~\centi\metre$
and height $H=[%H%]~\centi\metre$.
Which is the largest distance it can travel without turning?
[%
ans = {
right => '\sqrt{4 R^2 + H^2}',
wrong => ....
} %]
but now I have to print '\sqrt{4 R^2 + H^2}' in the formal solution (for
checking and for giving students the solution) and I also need the numeric
value of '\sqrt{4 R^2 + H^2}' for the multiple choice quiz.
I used to keep two versions: the latex and the perl one, but it was a mess
to keep them in sync, so I wrote a latex2perl translator (rather rough but
working).
