some thing like static blocks of java

Hi!

Not sure if it is good idea to apply OOAD Featurs to ant. But any way I posting 
this for a discussion and some conclutions there after..

I am looking for some kind of static targets, meaning how may ever time this 
targets called (using dependends attribute), but ant run time should run this 
target only once.

eg.

<target name="init">
</target>

<target name="src" depends="init">
</target>

<target name="packages" depends="init">

<target name="all" depends="src,packages"/>

when target 'all' is called init gets called twice, which could be avoided if 
static attribute is supported by ant eg. one could write static targets as 
<target name="init" static="true">
</target>

I do see some workaround like below which would have the same effect.. but I 
consider this as less readable

<target name="init" unless="isInitRanOnce">
<property name="isInitRanOnce" value="true"/>
</target>
