The language keywords are just keywords; you simply learn their meaning. As a native English speaker, though 'while' is a somewhat intuitively-named keyword, the 'for' keyword in c/c++ has to be learned. After a while you don't notice, any more than musicians have to learn Italian to play music (quick: what do 'fortissimo' and 'da capo ala fine' mean).

I don't see any problem with source code that says something like 'auto maßtab = waage.m_maßtab();' 'auto' and '=' are simply language tokens.
