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 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.
