At compile time the name of a variable, including the name of an instance of
a class, is known.  When the function of compiling and linking is done the
name is no longer known.

Nope.  Variable names don't exist at runtime, they are resolved to memory
addresses at compile time.

Just pass a string literal as another parameter to the constructor and use
that instead.

Variables have a very small scope compared to shared memory segments. 
Therefore, it wouldn't be a good idea to name shared memory segments 
after variable names: Better try to use unique names, created from a 
unique property of the variable to use, e.g. memory location, or a 
global counter.

However, you can enhance classes so that they register automatically 
with a list or container at creation. You'd of course have to hand over 
the name of the variable in an extra string, so that it can be stored in 
this list. In general, I really don't recommend that, but, of course, I 
don't know what you need that for.
