It is. The code of FINALLY is always executed before the CATCH. It is 
intended to clean up things before propagating or displaying the error.

The current problem is that the Error object is global, and so can be 
overrident during the Finally part. I will try to make it transparently 
local to the function, but I'm not sure that it is possible yet.
