How to template'ize variable NAMES, not types?

Question

my question is about how to template\'ize the name of a class member that should be used.

Maybe a simplified & pseudo example:

Answer 1

Template parameters are restricted to types, integer constants, pointers/references to functions or objects with external linkage and member pointers -- but no identifiers.

But you could use a member pointer as template parameter:

template
void doSomething(std::vector & all) {
   for( i=0; i < all.size(); i++)
      (all[i].*MemPtr)++;
}

:

doSomething<&MyClass::aaa>(all);

Note that I changed the doSomething function to take a reference instead of accepting the vector by value.
