				The core standard document defines &quot;type context&quot; in the definitions section. In that document, it is mainly used for disambiguation of enumeration literals, but the usage is the same for the @dynamic matching construct, i.e. the type where the @dynamic is used must be known, either from the place of usage (actual parameter to a typed formal parameter, right hand side of a typed declaration) or from prefixing it with the type in otherwise untyped contexts (like receive, log arguments or arguments of other operations that have no typed parameters like isvalue).<br />
<br />
Therefore, I think the standard is clear enough on that issue. We could do a slight rewording from &quot;a typed context&quot; to &quot;the context of a type&quot; (which is used in the definitions section), but I am unsure whether this will lead to a higher clarity.			</td>
