Of course in C++ and Rust you have function literals. In C++,


  auto f = [](auto a, auto b) { return a + b; };
  assert(f(3, 4) == 7);
  assert(f(3.25, 3.75) == 7.0);
  assert(f("3"s, "4"s) == "34");

Rust lambdas might be less versatile.

No, Rust Lambdas generally work the same as C++ lambdas - subject to the usual Rust rules about lifetime.
