Thanks @isuruf.

FWIW, I have come across another issue (still related to the minus operator; see https://github.com/opencor/opencor/issues/774).

Thinking more about it, I feel like we need to replace the default constructors that we use in our bindings with the `create()` method. Indeed, some classes (e.g. `Variable`) has...

Oops, just noticed that it looks like @hsorby thought about it (obviously! :p :)), as can be seen [here](https://github.com/cellml/libcellml/blob/90e4c8553dff3b360dee4edd967d97aecb1c90ee/src/bindings/interface/createconstructor.i). So, @kerimoyle, it looks like you need to update your [tutorial](https://github.com/kerimoyle/libcellml/blob/pr344_documentation/docs/tutorials/tutorial3/tutorial3_complete.py)...

Ok, it's not clear to me what is actually done in the bindings. So, going to leave it to @hsorby to comment on it once he's back. All I can...
