I understand you have this belief and find it incompatible with the LLVM
community. I think several folks have tried to persuade you that there is
merit in the design of LLVM here, but I understand you remain unconvinced.
Perhaps you will start a compiler project based on your convictions here
and develop it and show why that is a better way to start a compiler
project. But without actually contributing to LLVM and showing clearly (and
incrementally) how to improve it based on your belief with evidence to back
it up, I don't think reiterating your belief on the list is a productive
thing to do.
