Velocity isn't perl. it doesn't directly support recursive rendering,
nor will it.
you have two choices: either look into the RenderTool/ViewRenderTool
in the VelocityTools project. or if your rendering is truly as simple
as your example, you can just add the context to itself:
context.put("A", "B");
context.put("B", "C");
context.put("ctx", context);
then query it directly:
$ctx.get($A)
