One good thing with a code generation approach is that we can actually inspect into the generated code and see what's going to happen in a relatively easier way. And it's usually working nicely with static analysis. For abstract base class or whatever, it's kind of hard to do.

Of course, code generator (or even compiler) is harder to maintain, especially when you want the output to be human readable. So it's always about trade-off. Think about how many lines of code it's going to generate. If it's an order of 100k then it's usually worth the cost. 10k might be good to go. 1k, probably not.
