Typed Racket generates submodules, so that may cause this even if you<br>
don&#39;t write them explicitly.<br>

&gt; Yes  PR 13096 is the same error message that I&#39;m getting.  However, I&#39;m<br>
&gt; seeing this in my TR code.  I don&#39;t have any submodules in my code however,<br>
&gt; as TR submodules don&#39;t work,  so I think the problem is more generic than<br>
&gt; submodules in enter!.<br>

&gt;&gt; (that bug is due to an interaction between submodules and enter!)<br>
