Rethrowing exceptions with the exception parameter creates a copy of the exception and it should be avoided in favor of just using throw.
```c++
void f()
{
throw MyExpensiveExceptionType();
}
void g()
{
try
{
f();
}
catch (const MyExpensiveExceptionType& ex)
{
// throw ex;
// ~~
// ^ Re-throwing exception arguments causes a copy to be made
// Fix:
throw;
}
}
```
