According to this table https://software.intel.com/en-us/articles/c17-features-supported-by-intel-c-compiler Intel C++ 18.0 supports structured bindings, but when I compile the code below I get error messages.
#include <tuple> #include <iostream> #include <typeinfo> #include <string> using namespace std; int main() { tuple<int,string> t(1, "sldkfj"); auto [i,s] = t; cout << i << endl; cout << s << endl; }

That documentation link is wrong, 18.0 is based primarily on EDG 4.13, and we expect structured bindings will become available in EDG 4.14
Thanks for pointing this out, I'll see about getting that link corrected.

What are the upcoming featuresupport plans exactly?
Right now the adoption of standards lags quite some way behind of it's progression - compared to other compilers.
constexpr-if support was the least I'd been expecting from the new major release.
