why not supply a interface like:

Val& v = var.assign(val);

for simplity, and the unnecessary "get" is also elimited.

Such interface is not common for C++. Most programmers are used to the following:

class_name& class_name::operator=(const class_name&); or class_name& class_name::operator=(const class_internal&);

While you propose to implement `class_internal& class_name::operator=(const class_internal&);`

I don't think he's proposing that for operator=, but a not-yet-exist assign method. Seems reasonable to me, sometimes we do want to do some immediate operations after the assignment.
