By "given function", do you mean an arbitrary input function (something that supports __call__) or something in the finite element space?
Arbitrary input functions, or more(?) precisely, a function that we know how to evaluate at a point but not much more.
Functionals know how to apply themselves to the finite-dimensional space members via __call__ (it's just a dot product).
Yes, but we typically want to use this in order to interpolate functions onto the element spaces...
There is some preliminary support for the types of functionals in the "get_type()" method. It would need to be expanded to include some of this other information.
Yes, that is a starting point. If you think the idea sounds sensible, then I can take a shot at making it work?
