Ard, if the Exception class is not the base class of all exceptions(catch
all), it's very difficult to emulate "finally"(You must know every
exception that may be thrown inside the try block, and sometimes you
don't).
I really miss finally, since I'm developing a CORBA 2.3/3.0 extension for
PHP5 with an idl2php language compiler(translated from OpenORB). In the
compiler, for every try/catch that has finally, I have to place the
finally code inside every catch block, at the end of the try block and
before every return statement inside the "try" or "catch" block. It's
really a pain... But I can live with it by now. :-(

I agree.
