Description

From the Dept. Of "We did this in T4 and didn't know it was brain damaged then." ... various APIs related to translation and validation work by throwing a ValidationException which is nothing more than a wrapper around an error message string. It would be nice to allow, in some compatible way, allow methods to simply return the exception, or even just the string for the exception, rather than throwing an exception, which is very inefficient.
