Interesting article... He makes a pretty strong case for immutability and purity in D, actually. He didn't mention TLS, but with immutable, pure, and TLS by default, D could stand a pretty good chance of doing well with concurrent programming. The imperative paradigm may not be such a killer if you have TLS for almost all your data and keep most of your code pure. Even if it's not strongly pure, in many cases it's still thread-safe, unlike in C/C++ where the equivalent of __gshared by default means that if you want to do multithreading, your code is unsafe by default and you'll have a big headache trying to eliminate race conditions. This is a pretty valuable combination that D has, that we should pay more attention to; it has long-term benefits for D. T -- Shin: (n.) A device for finding furniture in the dark.
