>"As the OP was kind of insinuating just because many are too young to remember the OSes written in those languages, they should be ignored." No, I wasn't. It was an honest question. The only OSes I've used or had any experience with are Dos/Windows, MacOS, iOS, various Unix/Linuxes and the reaally old Commodores/Macs that just ran Basic. I was hoping maybe something I'd heard of wasn't based on C/C++.

Faire enough, so prepare for an history lesson. :) Mesa/Cedar was created at Xerox PARC, as an extension of the Xerox Star 8010 system, which was programmed in Mesa, the language that inspired Niklaus Wirth to create Modula-2. http://www.digibarn.com/collections/systems/xerox-8010/ http://www.digibarn.com/collections/systems/xerox-8010/ https://www.youtube.com/watch?v=Cn4vC80Pv6Q https://www.youtube.com/watch?v=Cn4vC80Pv6Q https://www.youtube.com/watch?v=ODZBL80JPqw https://www.youtube.com/watch?v=ODZBL80JPqw Mesa evolved to Mesa/Cedar, which allowed for automatic memory management via reference counting and a tracing collector for the cycles. https://archive.org/details/bitsavers_xeroxparcteCedarProgrammingEnvironmentAMidtermRepo_13518000 https://archive.org/details/bitsavers_xeroxparcteCedarProgra...
