Well, some more high level functions to diagnose memory usage, especially aids to help find memory leaks. Or not even necessary memory leaks, we may also want/need to reduce the memory footprint. Although objgraph is very helpful on its own it is still pretty low level and, for example, if we want to inject some diagnostic message somewhere in the code (e.g. “top 5 object types whose total size increased memory consumption since the last call”) we’d have to directly invoke objgraph and remember what exact parameters to use to achieve that. I think it’d be more convenient to have some more high-level functions that already encapsulate all necessary logic related to using objgraph and achieve what’s needed. Also, I wouldn’t want to spread out uses of objgraph all of the code, I would better have one module that uses it. Just to reduce coupling with a 3rd party lib.
Sorry if that sounds too abstract now, I’ll try to come with concrete examples to demonstrate what I mean.
