I was in a discussion with a member of the Go development team, bitterly complaining about their decision to go with a GC'd heap as the only way to access memory for something they intended as a "systems programming language". They suggested I link in C data structures for those heap-heavy caching applications :-( As I see it, C and C++ are the only practical options for writing high performance, memory efficient, cache heavy applications for production use in the current tech climate.
