This could require "operator auto".

btw recently I discovered that we already have this operator in C++,
but only for one thing: C arrays (value decay).
And as one goal of C++ is that user types should have the same
capabilities as built in then they should be able to deacy too.
Of course if used too much then it could be problematic, but if done
correctly then it would be more beneficial.
As arrays behavior is bad because they fit more C than C++, but user
types from the start will fit C++ more.
