[Martin Sandve Alnæs <martin.alnes@xxxxxxxxx>]

Changing repr is incorrect, and the bugs you're finding will never end.

It is a fundamental design choice in UFL to make everything
immutable, and the repr strings can never change. This is a
critical property for lots of things to work, and it is assumed
all over the place. It cannot ever be changed.

Instead of modifying an UFL object, always create a
new one with the changes you want. This is how every
algorithm in UFL works, and this is how every future
algorithm working on UFL objects must work.
