] | Don't even try. It won't work, and if you could make it work, it would be a bad thing anyway.
From the looks of things, your node is in something like a linked list. If that's the case, then what you normally want is something like:
```
template <class T>
class linked_list {
class node {
node *next;
... | The hidden parameter 'this' is passed with the 'const' qualifier. Hence it cannot be changed.

15,333,134 | I have a class like so:
```
class Node {
// data
Node* next;
void operator++(int);
};
```
And when I define the post-increment operator like so:
```
void Node::operator++(int) {
this = this->next;
}
```
I get the error `Expression is not assignable` on `this = this->next;`.

You have a `node` class which represents a node in the list. Typically one would also have an `iterator` class which represents the position in the list that you are currently at. It seems to me that you are trying to use `++` to iterate to the next ite... |
