I used the word *arguments*, not parameters. FWIW, *const* seems to
correspond to immutable, pretty well. I find Python to be more more
like Java, with regard to "passing objects by reference".

Bear in mind that you don't have to know every feature of a language to
make good use of it, unless, perhaps, that is your job. I don't believe
reading the latest "ISO-C++ draft" would be a good use of my time; it
sounds like a document geared more to compiler designers. I don't even
try to memorize <cmath>. If I need a function, I search for it.
There is a reason that C++, Java and Python all coexist. It might be
helpful for you to try to appreciate that.
