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);
