My code generator will generate Java nested classes. The problem is the
level of nesting can't be determined statically. So, the ideal case is I 
define a Java class template in ERB, which accepts binding variables as 
input
parameter, and in the template, it can "call" itself with new bindings.
Just like what does recursive function do.

I'm not sure if i can achieve this with "invoke arbitrary code". For
example, can I invoke the template itself with new bindings in the
template? Could you give me an example? Thanks!
