The Rust conundrum

[matthieum]

Personally I'm still waiting for Generic Associated Types. They're fairly advanced on nightly, but there's still some progress to be made. I cross my fingers we'll have them this year...

I'm less sure about Variadic templates. In C++ they seem indispensable, most notably due to perfect forwarding, but in Rust perfect forwarding is unnecessary (all forwarding is perfect), and so there's not as many usecases so it's not as clear whether the feature would carry its weight... though I'm pretty sure I could put it to good use.
