ufl function take supprisingly long to compile
Compiling a simple ufl expression into a bindable function object can take quite some time. The code generation does not seem to be the problem - going into the dune-py module and compiling by hand can take on my machine around 50sec. Compiling an integrands module is much faster so part of the problem has to be in the included headers files.
Reducing the compilation time would be helpful
