This doesn't work. `in` returns null when the key doesn't exist.
So you are de-referencing null:

is a new flag/method really that necessary? In my experience if
you have trouble naming it you haven't found its true purpose

My personal reason for not liking it is because the same name is
used by Microsoft:

I think I have clearly explained its purpose.
