Currently, the form pullbacks are hardcoded and somewhat implicit. This makes the code hard to read and prevents extensions to things like partial derivatives.
Describe the solution you'd like
An explicit pullback operator. This can default to the form pullback, but would allow other options for things like partial derivatives.
