The value of a dynamic property is indeed re-evaluated each time the
property is referenced. This behaviour is easily demonstrated with the
following build file:
<project name="dynamic" default="run">
<target name="run">
<property name="foo" value="Bah = [${bah}]" dynamic="true" />
<!-- This will fail: Property 'bah' has not been set.
<echo message="${foo}" />
-->
<property name="bah" value="1" />
<echo message="${foo}" />
<property name="bah" value="Not 1 any more" />
<echo message="${foo}" />
</target>
</project>
You could then use a dynamic property as an alias for a particular
function call... I'd suggest this isn't a wise thing to do, for much the
same reason as use of #define to alias function calls is a discouraged
practice.
