I was starting to think of something like this, but assumed (wrongly) that ^
would only mean start of string, at start of regex. Oops...

I'm sure you *can* grok it. It's very straightforward: match (almost)
any single character, then be at the start of the string. A clear and
obvious paradox, and hence unmatchable.
