<p>Sometimes a user offers an Answer which can be <em>proven</em> false, but the proof doesn't fit in the comment box. Is there a best practice for pointing this out? (I'm explicitly not asking about differences of opinion or judgement, but things that are provably true or false in a mathematical sense.)</p>
<ol>
<li>Offering the proof in a different Answer to the same Question doesn't seem like appropriate use of the Answer feature.</li>
<li>Breaking the proof into several comments is tedious and hard because the edit duration expires.</li>
<li>Asking and Answering a <em>new</em> Question, and then posting a comment that links to the new post seems like the best option.</li>
</ol>
<p>Have I missed a better alternative?</p>
