Auto-escape JSX under code listing?

[Huxpro]

Have we consider automatically escaping JSX under <pre><code>...</code></pre> or providing an emu-code with a similar functionality?

It will benefit proposals writing sample code with JSX such as do-expressions, pattern matching. I'm even thinking of using ecmarkup for the facebook/jsx github page itself.

Currently, one would have to manually convert them to HTML entities, which are not very convenient to read or edit it.
