Seems like a bug that we just introduced recently. I guess the need
for a regression test suite is needed now more than ever so that we do
not commit code that breaks the previously working features

The code should also perform all kinds of arithmetic on local
variables and parameters (notice that we dont have fields yet ;-).
You should also be able to invoke constructors and methods on other
interesting objects (although constructor handling for your own
classes has a bug right now that I will fix tomorrow).
