Hello Samuel,<br>
<br>
Example outside of xml "object" (lot of overloads)<br>
<tt>a = mlist(["toto", "id"], 1);</tt><tt><br>
</tt><tt>b = mlist(["toto", "id"], 1);</tt><tt><br>
</tt><tt>a == b -> [%t %t]</tt><tt><br>
</tt><br>
For mlist we compare the type ("toto") and fields ("id" in this
case)<br>
</blockquote>
<br>
and<br>
<tt>--> a = mlist(["aBcD", "id" "id2"], 1, 2);</tt><tt><br>
</tt><tt>--> a==a</tt><tt><br>
</tt><tt> ans =</tt><tt><br>
</tt><tt> T T T</tt><br>
<br>
OK: so<br>
a) there is actually a default equality definition<br>
b) it is actually type+fields-wise<br>
c) it looks not documented: none of the list, mlist, tlist,
overloading, comparison, and equal pages indicate it.<br>
d) it is overloadable:<br>
