Consistent extraction of subfunctions in UFL and PyDOLFIN

Registered by Garth Wells

In UFL, subfunctions are created by

u, v = split(U)

and in DOLFIN (Python interface)

u, v = U.split()

This is confusing, and there are some pitfalls. Can we improve it?

Whiteboard

Not sure, but we can keep it in mind when discussing multidomain stuff and mixed functions over subspaces etc. Our heads might explode in the process, but it's worth a try :)
