> Beyond what @Oscar_Smith pointed out, Chris has discussed in detail in multiple places that yes, he does not think julia is as good for writing high performance libraries as C++.

Mason was so kind as to elaborate in DM:

"It’s not about performance, it’s more about maintanability and reliable abstractions.

A lot of the things one does in julia for performance are not really guarantees, but just doing things and hoping the compiler cooperates. That’s fine for applications, but can be quite rough for maintaining a library that many other people depend on."
