Machine code was never meant to be readable but high level languages can and should be ;-).... on the serious side of the debate there are reasons for shying away from code generators in my case that are currently proprietary (some of the lesser results will likely be FOSS'ed though)... the main reason is we need to (in some cases) deal with multiple languages in the same compilation unit and have developed fairly good (at least in theory and my "fun work" is really nothing more then a proof of concept, without the pressure of deadlines and such, with Java as a typical non-trivial language to work with from the compiler POV)... due to the above using a parse generator would make it very inefficient to create the needed parsers since they are (by there very nature) very non-OO in how they deal with more then one grammar at once... namely they are designed to deal with single languages at a time and not "families" of them
