				Let look at the first case:<br />
1. <br />
alt {<br />
[] PCO1.receive(MySig3) {<br />
&#160;&#160;&#160;PCO2.receive(MySig4);<br />
&#160;&#160;&#160;PCO2.send(MySig5);<br />
&#160;&#160;&#160;PCO2.send(MySig6);<br />
&#160;&#160;&#160;PCO2.receive(MySig7)<br />
}<br />
<br />
as a standalone receive is a shorthand for an alt with a single receiveing branch, the above is the same as:<br />
alt {<br />
[] PCO1.receive(MySig3) {<br />
&#160;&#160;&#160;alt { [] PCO2.receive(MySig4){} };<br />
&#160;&#160;&#160;PCO2.send(MySig5);<br />
&#160;&#160;&#160;PCO2.send(MySig6);<br />
&#160;&#160;&#160;alt { [] PCO2.receive(MySig7){} }<br />
}<br />
<br />
your proposal is:<br />
alt {<br />
[] PCO1.receive(MySig3)<br />
{ <br />
&#160;alt {<br />
&#160;&#160;[]PCO2.receive(MySig4) {<br />
&#160;&#160;&#160;PCO2.send(MySig5);<br />
&#160;&#160;&#160;PCO2.send(MySig6);<br />
&#160;&#160;&#160;PCO2.receive(MySig7)\<br />
&#160;&#160;&#160;&#160;&#160;//this receive can also be extended to an alt with a single branch<br />
&#160;&#160;}<br />
}<br />
<br />
<br />
i.e. all activated defaults in both cases will be invoked for both the PCO2.receive(MySig4) and the PCO2.receive(MySig7) statements (separately, of course). Thus, I cannot see how the behaviours of the current example and the proposed changed example differ.			</td>
