[Vala] What is the right syntax for defining pointers or references or "aliases" in Vala ?

[Serge Hulne <serge hulne gmail com>]

What is the Vala syntax to express that :

b is a alias of a (or b points to the same address that a or b is a
reference to a).

Is there a way to express this in vala or does *assignment always mean
memory allocation* in Vala.

In other terms : How do you store references to variables (or pointers
to variables) in, say, a container (a libgee data structure) while
avoiding duplication of said data.

In C or C++ this would be done with pointers (or references).


Serge.
