Bjarne Stroustrup writes "Within C++, there is a much smaller and cleaner language struggling to get out." and I think I can see elements of that language in newer and newer editions. It's nice to have both the new and the old in the same toolset, although sometimes I look at Rust and I think "this might be better in a newer manual-memory language".
Concepts: finally
other language features: nice
library features: okay
what was left out: I have to wait ANOTHER three years for reflection?
ABI: just break it already, cowards.
overall: how long 'til I get it?
