Your proposal about invariant generics is about ''conformance'' between generic parameters, i.e. conformance between &amp;lt;e&amp;gt;X [A]&amp;lt;/e&amp;gt; and &amp;lt;e&amp;gt;X [B]&amp;lt;/e&amp;gt;. What I'm trying to point out is the ''use'' of features on a formal generic parameter which are covariantly redefined. The possible solution for ''like Current'' features with the monomorphic keyword is about the instantation of the generic. A monomorphic generic can only be instantiated with a monomorphic type.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td colspan=&quot;2&quot;&gt;&amp;#160;&lt;/td&gt;&lt;td class='diff-marker'&gt;+&lt;/td&gt;&lt;td style=&quot;color:black; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;&lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td colspan=&quot;2&quot;&gt;&amp;#160;&lt;/td&gt;&lt;td class='diff-marker'&gt;+&lt;/td&gt;&lt;td style=&quot;color:black; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;&lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;You can also look at it that way: With your ''invariant'' generic, you can use the generic as a feature argument. With a ''monomorph'' generic, you can call covariant features which have ''like Current'' in the argument.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
