Another schoolboy question.
Suppose I am constructing a tree (in this case it is an AST).
In C I
would have a pointer for the child to find the parent, and an
array or
linked list of pointers to find the children from the parent.
Obviously, I could still use pointers, but that would not be
idiomatic.
Not true. If you're using a tree structure, you *should* use
pointers.
Unless you're using classes, which are by-reference, in which
case you
can just use the class as-is. :-)

The GC is allowed to move structs around, as I undestand it.
Under what circumstances do I get into trouble having a pointer
to them?
