 * smacro try_assign - Assign the evaluation of the try-catch
 *
 * @assign_to: Where the evaluated value is stored in.
 * @try_body: Expression making up the try body.
 * @catch_body: Epxression making up the catch body.
 *
 * Description: Executes a try catch statement. If there was no error,
 * a provided variable is assigned to the evaluation of the try body,
 * otherwise to the evaluation of the catch body. This assumes that the try and
 * catch body are meant to return a value. If they do not, then do not use this
 * macro. If either of the bodies do not return a value, then a compilation
 * error occurs.
