A agree it's important for use Map/List in interfaces, so the
implementation is flexible.

But for internal usage (fields and local variables), I prefer
declaring the concrete class, because method calls are faster than
interface method calls. That means calling list.size() is a bit faster
when list was declared as an ArrayList.
