### [[temp]]: templates <a id="diff.cpp20.temp">[[diff.cpp20.temp]]</a>
|
| 2 |

|
| 3 |
+
**Change:** Deducing template arguments from exception specifications.
|
| 4 |
+
**Rationale:** Facilitate generic handling of throwing and non-throwing
|
| 5 |
+
functions. **Effect on original feature:** Valid ISO C++20 code may be
|
| 6 |
+
ill-formed in this revision of C++. For example:
|
| 7 |
+
|
| 8 |
+
``` cpp
|
| 9 |
+
template<bool> struct A { };
|
| 10 |
+
template<bool B> void f(void (*)(A<B>) noexcept(B));
|
| 11 |
+
void g(A<false>) noexcept;
|
| 12 |
+
void h() {
|
| 13 |
+
f(g); // ill-formed; previously well-formed
|
| 14 |
+
}
|
| 15 |
+
```
