This is not pedantry. I don't think this is as trivial as you seem to be implying. Unless you have a proof, you are just handwaving. Anyway, you are free not to elaborate, and I am free to leave the downvote intact.

Please take at least a day or two before accepting an answer. In this case, the accepted answer is incomplete.

The heuristic is only a first step. Making it rigorous is the hard part. -1 till there is a proof. Sorry.

@AstroNauft: You don't need to determine anything. It is a non-constructive proof. $L$ could be any language.

comment How to show that $\lim_{n \to +\infty} n^{\frac{1}{n}} = 1$?
@ADG: It is my name, I will spell it as I want! :-). Just kidding :-). Apparently, it is actually Aryabhata and not Aryabhatta. In fact I had it as Aryabhatta till ShreevatsaR corrected me.
