How should I compare immutable ints to ensure that they are actually
equal?
I was quite surprised to receive the following error message:
cbt2.d(732): Error: function object.Object.opEquals (Object o) is not
callable using argument types (immutable(int))
when I tried to assert that two values were equal. They were (should
be), indeed, immutable ints, but I'd prefer that I could check that
they were equivalent without printing them both out. (I'm having a
bit of trouble keeping my logic straight, so I'm trying to assert
many things that should obviously be true. And sometimes I've been
surprised.)
The error quoted above suggests you are trying to compare an object
type with an int. Can you give some more context? You can do that,
but you have to overload opEquals.

Thanks. That was the answer I couldn't see. I read it as complaining
about comparing two immutable ints, but
assert (nodes[root2.pg.pgNo] == root2.pg.pgNo);
should have read
assert (nodes[root2.pg.pgNo].pg.pgNo == root2.pg.pgNo);
