I'm not sure I am; the current behavior is almost always surprising and unexpected. You effectively need to keep a list in your head of everything that will clear your clipboard, which is really a list of everything that could ever cause problems, more often than not a flag that is entirely unrelated to your actual intent/action.

You might as well have it clear the clipboard if your next action isn't immediately paste and be done with it. Just don't bother to set the expectation that pasting will work like elsewhere.
