How can you get the number (and possibly names) of applications / sites associated with an application pool?

Question

If you have an application pool name and you can therefore retrieve this application pool is there any way to retrieve the applications or sites associated with this application pool programmatically? I would settle for just getting a number to basically identify if the application pool is being used but it would be nice to also be able to identify the name of the application / site that is using it as well if possible.

I came across this question but it seems to do it by looping through the existing applications. It doesn't address sites, though that shouldn't be tricky as I can use site.ApplicationDefaults.ApplicationPoolName. However, is there a 'clean' way of getting a collection of applications / sites if you have the app pool name?

After much time searching I couldn't find a specific way other than looping as suggest in my question. This was reiterated by Nicolas R.
