Classic bind is bad. Don't use it. It's hard to understand, hard to optimize, and lambdas are better in basically every way.

Related: is bind_front/back as bad from an optimization point of view?

thats quite some build-up regarding std::bind usefulness and then all we get is a single short sentence?
huh?

having never used bind expressions myself, i was tempted to believe this works, but it seems the nested bind example doesnt compile anyway?

Yeah, std::bind only transforms the bound arguments. It doesn't transform the function object.
