Executing a method via scripts instead of manually with reflection

I feel like this might be possible with the new script api (templates) but just not sure how to piece it together. If I store a class type, method name, and argument list values, I can use reflection to execute it with the awesome reflection tools Service Stack already has. What I’m wondering is if this can be done via scripts by saving only the expression<action> string (ie x=>x.DoSometing(1,2,class) and parameter values and pass them to a JS.eval or script. Is this possible?

Can you provide a real method example of what you mean?
