I wonder how generic are the snippets used - for some types of snippets, it might be possible to put some code around the original snippet directly in the snippet. That would alleviate the need to add a new API. But presumably it would only work for some types of snippets.

For the API itself - just an idea, would having a method `doInvoke` along these lines work:

public Object doInvoke(Method m) throws Exception {
    return doitMethod.invoke(null, new Object[0]);
}

?
