Are there any plans to provide some sort of debugging tools for Appian expressio

I'm already using both. The expression rule interface only confirms that the right number of parts are used for a function and that the parenthesis match. The text editor allows me to match up the parenthesis, but obviously has no idea if the expression is actually valid. I also create temporary columns in a report to test specific parts of an expression, but there are too many cases where an expression part won't work on its own, forcing me to debug the whole thing.

The ability to actually run an expression step by step would be a huge help--and something that most modern programming packages have.
