But only when they are actually used!

... really elegant.

They are concepts that are not really necessary with local
storage, that I do not really want to explain to other people.

The driver solves the PDE given by the first form in forms. This is a
first step towards instationary problems.

Some work on parameter classes, a bugfix on the splitting algorithm
some simplifications in the generation stage

I suspect it to account for some problems!
