I still give up on this, but if someone want this= , I grant right to to that.

And a few thing for th= e record.

In my eyes it is insignificant but there= are some peoples who are waiting for opportunity to exaggerate.

Scenario C++17:

for= ( auto& iter: std::as_const( cont ) ){
=C2=A0 //.. what ever
=C2= =A0}

Compiler must enter in as_const to see what is inside and at the end it will optimize = as we want/expect.
But this require some time.

Th= is proposal scenario:
=C2=A0for( au= to& iter: const( cont ) ){
=C2=A0=C2=A0 //.. what ever
=C2=A0 }

Compiler will just add 'const', No optimization of an= y kind.
Much faster than c++17.

And again some pe= ople are very peaky regarding even for a smallest thing.
'goto' is almost banned, I have compl= ain on using 'continue'= ..

'Companies rules' ( famous experiment with monkeys ) is fac= t, similarly it is time to have 'C++ ( monkey ) rules'.
