Orca, a distributed language designed by Henri Bal at the VU in
Amsterdam had a general 'graph' type that gave you pointers without
all the problems associated with them.

The idea is that a graph is an unstructured set of dataitems with an
associated method to allocate and deallocate new items. You can have
pointers to the items in a graph, but they are only valid in the
context of that graph. This way, all the headaches usually associated
with pointers disappear.

I don't know whether Henri invented the graph idea or got it from
somewhere else, and I don't have the thesis or papers handy to check...
