not my first rodeo! ABEL was the first language I designed (for Data I/O) back in the 80s.
ABEL = "Advanced Boolean Expression Language", a language for programming PLDs (Programmable Logic Devices) which was a core business for Data I/O.
There's no substitute for decades of having programmers giving you (and shouting at you) blunt feedback on your programming language proposals.
People have never been shy with criticism!
I did not know who you were at first. Would you have any thoughts on why another group made Golang when D already existed that you would be willing to share?
Because Google saves us all.
Because Go designers don't like OOP and didn't want low-level system programming as core features. They also were not keen on generic programming. Basically they wanted a simpler language. (Then they realized generics are useful, ironically their constraints add complexity). Also they wanted a segmented stack and coroutines + channels as language features.
