<p dir="auto">From <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="52218177" data-permission-text="Title is private" data-url="https://github.com/microsoft/TypeScript/issues/1524" data-hovercard-type="issue" data-hovercard-url="/microsoft/TypeScript/issues/1524/hovercard" href="https://github.com/microsoft/TypeScript/issues/1524">#1524</a>, I see that the default method are all "virtual", but sometimes I don't wanna some public method to be overidden. Would you invent a mechasim to force the users that they cannot override a public method (with the key word, something like "sealed")?</p>
