I see.

So as an example of doing both, consider following Java pseudocode (simples example that comes to my mind now):

  Foo value = someCondition()
              ? map1.computeIfAbsent("key", defaultValueProvider)
              : map2.computeIfAbsent("key", defaultValueProvider);

This both gets a value and changes state of the map; which map is queried/altered is determined by the condition. I personally don't mind such code, and prefer it to if/else version.

Shouldn't that be:

  Foo value = ( someCondition() ? map1 : map2 ).computeIfAbsent("key", defaultValueProvider);

Or some kind of moral equivalent?

Could be, though this is an artifact of a simplified example that I didn't mean to be relevant here.

For clarity, let's rewrite it as:

  Foo value = someCondition()
              ? map1.computeIfAbsent("key", defaultValueProvider)
              : list1.get(42);
