hi! I have another short newbie question. Why does the wrapper Symmetric() disappears, when one creates an uninitialised Symmetric matrix using a function similar()? This happens if dimensions are changed, see the matrix b2.

```
a1=randn(3,3)
a1=Symmetric(a1+a1')
b1=similar(a1)
typeof(b1)
a2=randn(3,3)
a2=Symmetric(a2+a2')
b2=similar(a2,2,2)
typeof(b2)
```

Does that have an effect on type-stability?

```
e=randn(2,2)
e=Symmetric(e+e')
b2.=e
```

Thanks
