Hello,
Sorry it's been so long since my last reply. I've been somewhat busy
around the holidays, but I hope to work more soon.

Yes, probably a good idea.

I don't think there's a functional way to do this, although I could be
wrong. What I want to do is make a structure where the child tree
nodes are linked to their parents. I can't get the address of the
parent until after I allocate it, so I allocate it with an empty list
of children, then use its address to make the list of children that I
want.
Another approach would be to make the list of children before
allocating the parent, but then I would have to go back and fix up
their 'parent' pointers. So I think either way I'm stuck doing some
mutation.

Ah, thanks. Done.
