+<h2>Natural Syntax</h2>
+<p>The plan is to support more natural (pure Java) syntax in conditions.
+To do that, the condition class is de-compiled to a SQL condition.
+A proof of concept decompiler is included (but it doesn't work yet).
+The planned syntax is:

+<pre>
+long count = db.from(co).
+    where(new Filter() { public boolean where() {
+        return co.id == x
+            &amp;&amp; co.name.equals(name)
+            &amp;&amp; co.value == new BigDecimal("1")
+            &amp;&amp; co.amount == 1L
+            &amp;&amp; co.birthday.before(new java.util.Date())
+            &amp;&amp; co.created.before(java.sql.Timestamp.valueOf("2005-05-05 05:05:05"))
