This:
\begin{juliaconsole}
rand(100);
\end{juliaconsole}
Prints 100 numbers in my latex document.
I noticed in the slides in your JuliaCon talk that a semicolon does suppress output. Any ideas what is going on here? I did find that this
\begin{juliaconsole}
rand(100); nothing
\end{juliaconsole}
Suppresses output. But, this is of course undesirable in a document.
