That's right, you're doing the .NET translation, I forgot.

Nope, and it's a big failing.  MASON and ECJ both badly need a testing  
regimen.  As they're academic projects, our major source of funding  
for such things are grants.  MASON's got a small NSF grant approved  
for exactly, but with the budget cut at NSF it's looking unlikely to  
be awarded.  Which means that they'll have to wait unless others can  
start pitching in.

Last year I built an extensive manual for ECJ, which required me to go  
through ECJ with a fine-toothed comb, kicking up a variety of  
(thankfully minor) bugs and misfeatures.  It was an enormously  
valuable exercise.  I'm now doing the same thing with MASON but it's  
taking quite a long time given my current academic schedule.  So  
anyway, it's high on the list.

Tests for complex 70K system are nontrivial!

As I've mentioned before, you are totally nuts.  :-)  Good luck!
