Work is almost complete on native code compilation (via C code extraction), allowing you to compile all the constructions you can formalize in Lean directly to native code. (see &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;leanprover&amp;#x2F;lean&amp;#x2F;pull&amp;#x2F;1241&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;leanprover&amp;#x2F;lean&amp;#x2F;pull&amp;#x2F;1241&lt;/a&gt; for progress)&lt;p&gt;(Note that none of those code extractors are verified to be correct themselves, lacking a formalization of the target language&amp;#x27;s semantics. You don&amp;#x27;t get a mathematical proof that the code you&amp;#x27;re running does what you specified, but you get &lt;i&gt;pretty damn close&lt;/i&gt;.)</text><parent_chain></parent_chain></comment><story><title>Coq-based synthesis of Scala programs which are correct-by-construction [pdf]</title><url>https://cedric.cnam.fr/fichiers/art_4027.pdf</url></story>
