<pre>
    In [this post](https://discourse.llvm.org/t/rfc-index-dialect/65540/35?u=_sean_silva) there was a mention of "dialect extensions", which seems like a really cool functionality. But I didn't find any docs for this feature, so I have no idea if it can solve my problem or how to do so.

We should have docs for this feature.
