#### `ranges::iter_move` <a id="iterator.cust.move">[[iterator.cust.move]]</a>

The name `ranges::iter_move` denotes a customization point object
|
| 4 |
+
[[customization.point.object]]. The expression `ranges::iter_move(E)`
|
| 5 |
+
for a subexpression `E` is expression-equivalent to:
|
| 6 |
+
|
| 7 |
+
- `iter_move(E)`, if `E` has class or enumeration type and
|
| 8 |
+
`iter_move(E)` is a well-formed expression when treated as an
|
| 9 |
+
unevaluated operand, with overload resolution performed in a context
|
| 10 |
+
that does not include a declaration of `ranges::iter_move` but does
|
| 11 |
+
include the declaration
|
| 12 |
+
``` cpp
|
| 13 |
+
void iter_move();
|
| 14 |
+
```
|
| 15 |
+
- Otherwise, if the expression `*E` is well-formed:
|
| 16 |
+
- if `*E` is an lvalue, `std::move(*E)`;
|
| 17 |
+
- otherwise, `*E`.
|
| 18 |
+
- Otherwise, `ranges::iter_move(E)` is ill-formed. \[*Note 1*: This case
|
| 19 |
+
can result in substitution failure when `ranges::iter_move(E)` appears
|
| 20 |
+
in the immediate context of a template instantiation. — *end note*]
|
| 21 |
+
|
| 22 |
+
If `ranges::iter_move(E)` is not equal to `*E`, the program is
|
| 23 |
+
ill-formed, no diagnostic required.
