But Derek, now I'm not passing variables a references (not possible in
current Euphoria), and I still think I need better tracing (this is so
because I am not doing commercial programming, some special kind of CPU
intensive programs).
Moreover, now you have
a = foo(b, c) and of course have 'a' updated.
Is it so big the difference with:
foo(a, b) where you can have 'a' and 'b' updated?
