Just go ahead and commit. I guess there are going to be not much
changes outside a separate optimizer file on this branch.

I tried compilation of this line of code alone. Strangely it compiles!
There has to be some bug in the parser. Are you able to prepare a
testcase for the standalone compiler, where it fails (you can use
-ignore-confusion option for ncc to print out the stack trace)?
