Scott, do not give up hope! You can implement a generic get(String)
method which can provide this functionality in a dynamic fashion:
public class Ident
{
public Client get(String name)
{
...
}
}
$ident.foo will map to Ident.get("foo"), which you can in turn have
return your Client object. Here's a link to the gory details:

velocity/src/java/org/apache/velocity/runtime/parser/node/GetExecutor.java?rev=1&view=auto>
And an example of an implementation which I use every day in production
for L10N:
