Yea, I played with it in 2011, but the compiler has changed since 
then, so I don't know how it is done anymore.

One of the post-semantic visitor classes surely though. None of 
those existed back then, but they actually should make it easier 
than it used to be. This is after compiler lowerings and error 
checks.
