I remember Pascal compiling crazy fast compared to C/C++. Partly because the language was designed to be easy to parse, but I assume part of the speed came at the cost of producing less optimal code.

But if most of your compiles are during development and debugging where optimization is less important, wouldn't it be nice to have super fast compilation during those stages? I don't know if any other compiled language comes close to Pascal in that regard.

A faster codegen backend for debug builds is in the works.
