[[expr.cond]] **Change:** A conditional expression with a throw
|
| 4 |
+
expression as its second or third operand keeps the type and value
|
| 5 |
+
category of the other operand. **Rationale:** Formerly mandated
|
| 6 |
+
conversions (lvalue-to-rvalue ([[conv.lval]]), array-to-pointer (
|
| 7 |
+
[[conv.array]]), and function-to-pointer ([[conv.func]]) standard
|
| 8 |
+
conversions), especially the creation of the temporary due to
|
| 9 |
+
lvalue-to-rvalue conversion, were considered gratuitous and surprising.
|
| 10 |
+
**Effect on original feature:** Valid C++11code that relies on the
|
| 11 |
+
conversions may behave differently in this International Standard:
|
| 12 |
+
|
| 13 |
+
``` cpp
|
| 14 |
+
struct S {
|
| 15 |
+
int x = 1;
|
| 16 |
+
void mf() { x = 2; }
|
| 17 |
+
};
|
| 18 |
+
int f(bool cond) {
|
| 19 |
+
S s;
|
| 20 |
+
(cond ? s : throw 0).mf();
|
| 21 |
+
return s.x;
|
| 22 |
+
}
|
| 23 |
+
```
|
| 24 |
+
|
| 25 |
+
In C++11, `f(true)` returns `1`. In this International Standard, it
|
| 26 |
+
returns `2`.
|
| 27 |
+
|
| 28 |
+
``` cpp
|
| 29 |
+
sizeof(true ? "" : throw 0)
|
| 30 |
+
```
|
| 31 |
+
|
| 32 |
+
In C++11, the expression yields `sizeof(const char*)`. In this
|
| 33 |
+
International Standard, it yields `sizeof(const char[1])`.
