+The reason this does not generate events is that in many cases that would introduced more problems than the event solves.
 A typical case is a flow equation of the form \lstinline!abs(x)*x=y!.
 If we have to solve for \lstinline!x! and had events for \lstinline!abs(x)! we would not find a solution if \lstinline!y! passes through zero.
