No, you need to structure your data in a way that there is almost no boilerplate, and only very little glue code (which effectively amounts to "the macro code", with the difference that it's only executed once per data object).

Good point, but I have a strong belief that the abstractions offered by C (function calls and good syntax for arrays and records) are sufficient and going up is detrimental for larger systems. I don't code in assembler because typically there is too much redundancy (function call convention) and it's too specific (architecture dependent) and probably too verbose. That said, I'm not strongly against it, but haven't really tried.
