It was requested but rejected for Ant2.
In your case, since you're passing a property on the command-line anyway,
if you define it as -Dbuild.for="Dev", couldn't you just do:
<property name="app.deployment.dir"
value="/opt/deployment/for${build.for}"/>
and eliminate those other two properties altogether?
