--- Comment #2 from Matt Kline <mkline at cs dot wisc.edu> 2012-03-23 13:16:23 UTC --- Would it be possible to at least make the exception that is being thrown more descriptive? I had guessed that some kind of compile-time warning might be impossible, but my main concern is that the exception that gets thrown offers little insight on what the problem might be.
