Make this a variable / macro and define these all at one place in this file. They will be dependent on the SymEngine version, but I think that's fine. If this becomes a problem, we can revisit the SymEngine API then.

Sure. I'll look into this!

You can use basic_get_class_id("Integer") to get the value.
