<p><span class="h-card" translate="no"><a href="https://types.pl/@bhaktishh" class="u-url mention">@<span>bhaktishh</span></a></span> The way I think of it (probably there are better explanations out there): in impredicative type theories you have a universe that can quantify over all type universes; in a predicative type theory, trying to quantify over the type universe puts you one universe higher.</p><p>System F has impredicative quantification. MLTT with Type:Type has impredicative quantification. CoC has impredicative quantification via Prop.</p><p>Whereas MLTT with a strict universe hierarchy is predicative.</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@dabeaz" class="u-url mention">@<span>dabeaz</span></a></span> It’s baffling that </p><p>class Point(dataclass): x: int; y: int;<br />or<br />class Point(metaclass=dataclass): x: int; y: int;</p><p>doesn’t work. Isn’t that the point of subtyping or submetatyping?</p>

<p><span class="h-card" translate="no"><a href="https://types.pl/@ionchy" class="u-url mention">@<span>ionchy</span></a></span> mostly trying to get into the weeds of LF / CoC so kind of both ? but LF for now so predicative</p><p>what im getting is &quot;you can&#39;t construct x : T if x : \forall T. T&quot; but im trying to concretize it</p>

I feel like when you shake up groups of people all the neurodivergent folk tend to find themselves clumped together like the smaller crumbs in a cereal box.</p>

<p><span class="h-card" translate="no"><a href="https://types.pl/@ionchy" class="u-url mention">@<span>ionchy</span></a></span> i always ignore your posts that have &quot;impredicative&quot; in them and now im regretting</p>

<p>&quot;Predicative mathematics is a way of doing mathematics without allowing impredicative definitions.&quot; absolute banger from nlab right here</p>
