In this example, the count should be 9 (from the doubles) + 7 (from the
user-defined class sym).  But instead each sym counts only as 1 and we see 11

>> whos
Variables in the current scope:

   Attr Name        Size                     Bytes  Class
   ==== ====        ====                     =====  =====
        A           3x2                        240  sym
        d           3x3                         72  double
        x           1x1                         30  sym

Total is 11 elements using 342 bytes

@mtmiller found this looking at a related bug:


There is a minimal class that demonstrates this problem in that bug.

In that other bug, I said:

> The number of elements thing is counted by adding up
> the ".capacity" of each varval. So I guess "capacity"
> is wrong for simple classes.
