So Jurg and Wirth designed Modula-2 as a replacement, then built a computer, then wrote an OS, wrote some apps, and lived happily ever after. Until their urge to build new languages was overpowering. Rinse, repeat.<p>Yet, Modula-2 had a nice combo of readability, safety, compiler efficiency, and runtime-efficiency. Proven in OS development. Such safe, systems languages helped once I got past toy problems C could handle without crashing my stuff. ;)
