Minimize private alias declarations and static constants?
Currently, each Dumux class that takes a TypeTag as template parameter typically contains several/many private alias declarations and static constant definitions extracted from the TypeTag. This may happen hundreds of lines above the first usage of the declared names.
An alternative would be to put the declarations as close as possible to the place where they are used. If the declarations are used as function parameter / return types, one could use template parameters / auto instead.
The expected benefit would be an improved readability of the code and the avoidance of unused declarations and definitions.
In order to discuss this, I set up !741. Please have a look and share your opinions here.
