ANT How to use the lexically scoped properties in Ant 1.8?

I have script that dosn't work becouse property once set became unwritable

<target name="test" >

    <fileset id="dir1" dir="./dir1"/>
    <fileset id="dir2" dir="./dir2"/>

    <pathconvert property="path.converted" refid="dir1"/>
    <echo message="${path.converted}"/>
    <property name="path.converted" value="set this property manually"/>
    <echo>${path.converted}</echo>
    <pathconvert property="path.converted" refid="dir2"/>
    <echo message="${path.converted}"/>
</target>

always echoed the same result, but I want that echoes was different

I read in Apache Ant 1.8.0 release, that

Lexically scoped local properties, i.e. properties that are only defined inside a target, sequential block or similar environment. This is very useful inside of s where a macro can now define a temporary property that will disappear once the task has finished.

How to use them?

I would simply use different names for path.converted for the example above.
path.converted.1, path.converted.2 etc.

If you would have created a macrodef you should definitely use the local task to make the property local.

I found solution. Use local task 

<target name="direct" depends="">

    <fileset id="dir1" dir="./dir1"/>
    <fileset id="dir2" dir="./dir2"/>

    <!--<property name="path.converted" value="0"/>-->
    <local name="path.converted"/>

    <pathconvert property="path.converted" refid="dir1"/>
    <echo message="${path.converted}"/>
    <local name="path.converted"/>
    <property name="path.converted" value="0"/>

    <echo>${path.converted}</echo>
    <local name="path.converted"/>
    <pathconvert property="path.converted" refid="dir2"/>
    <echo message="${path.converted}"/>

</target>
