+Even the combination of `unflatten` and `evaluate!!` tends to be faster than a single call to `init!!`, especially for larger models.

 If you use it, you must pay close attention to correctness:**
 
 1. For models with multiple variables, the order in which these variables occur in the vector is not obvious. The short answer is that it depends on the order in which the variables are added to the VarInfo during its initialisation. If you have models where the order of variables can vary from one execution to another, then `unflatten` can easily lead to incorrect results.
