> Mainly because error reporting and performance, both compile-time and run-time, is hard to achieve. Do you have more information on the error reporting bit? Is it due to losing important metadata during compilation? If so, couldn't a different, more metadata-rich representation than the basic AST most of us are familiar with help here?
