I've said a couple of times that new language designers should thank their lucky stars that C++ has set the bar for "fast compilation" so low. Coming out of the gate with a compiler that's "faster than C++!" is pretty doable even for a relatively compile-time heavy language. If you had to come out of the gate with something as fast as Delphi to be taken seriously, we wouldn't get very many new languages.

(I mention this in the context of my observation that the minimum bar to be taken seriously for a language is going steadily up. You certainly need a standard library that is powerful out of the gate, whether or not it is necessarily "part" of the language, and we're getting perilously close to the language being required to ship some heavy-duty HTTP stuff, possibly a server implemented in the language, before it stands a chance. Rust may have snuck in under the wire on that, though of course that stack is developing apace even so.)
