[Dune-devel] Reference and pointer type when dereferencing EntityPointer

[Steffen Müthing]

Hi,

to my rather big surprise I just learned that operator* and operator-> in the EntityPointer facade
have always returned the Entity by non-const reference / pointer. It has been like that pretty much
forever (those lines were last changed in 2005!).

Is there a good reason to return a writable reference?
