But even then, there's degrees of knowledge and familiarity within that. For example, in Python, is using the `else` block of a for-loop clever? It's a part of the language that I'm familiar with - in principle it's just domain knowledge. But I've worked with plenty of Python devs who've never seen or used that construct before. For them, it's often black magic, and a classic example of "clever" code. The point is that everyone judges cleverness based on what they know and are familiar with. If I need to think too hard to understand it, then it's clever code. But everyone has different levels of familiarity and experience, which means that cleverness is always an individual metric.
