<br />
&gt; List subtyping is [not] possible [on] the declaration of the first parent type<br />
<br />
Does this mean that the first subtype declaration is not allowed to have a value constraint?<br />
<br />
&#160;&#160;&#160;&#160;type record of charstring MyRecordOf ({&quot;aa&quot;, &quot;bb&quot;}) // constraint not allowed?<br />

If find the subtyping rules difficult to comprehend and to reason about. I believe a we could simplify sections about type handling (subtypes, compatibility, equality).<br />
