Re: Why VAX Was the Ultimate CISC and Not RISC

There is a language (C++) which has introduced reference operators that
distinguish between “move semantics” versus “copy semantics”.

This is the first time I read about copy semantics; the thing that is
not reference semantics is usually called value semantics.  But a web
search indeed turns up uses of "copy semantics".  Interestingly, it
also turns up a link to a web site from the C++ standards committee:

https://isocpp.org/wiki/faq/value-vs-ref-semantics

The title says: "value vs ref semantics", and while there are 11
occurences of "copy" on the page, "copy semantics" does not occur
once.  However, it does say

|Value (or "copy") semantics

so apparently "copy semantics" is a synonym for "value semantics".
