The phrase "A Modest Proposal" is generally associated with the essay's author, Jonathan Swift. By combining that phrase in a literal sense ("I'm suggesting something new about how to handle option methods") with the name of a programming language which coincidentally is the surname of the author, it leads to a clever connection.
It would be like an article called, "Do not cast your Perls before swine" about dynamic casting which also is a play on the common phrase, "Do not cast your pearls before swine." [Yeah, that example kind of sucks but it was the first thing that popped into my head.]
You're right, it would be like that hypothetical article if you both made up a clever title involving perl and casting and the modest proposal thing was particularly clever. But it's not, so that hypothetical rather begs the question.
