panic: *ssa.UnOp during rows.Close()

[nelsam]

The following code seems to cause sqlrows to panic:

rows, err := db.Query(a, b, c)
if err != nil {
    return err
}
func() {
    defer rows.Close()

    // read from rows...
}()

After digging in some, it seems that the deferred rows.Close() call inside of the closure is dereferencing the *sql.Rows value, because it comes out as an *ssa.UnOp instead of an *ssa.Extract.
