<pre>Implicit conversion from int to double generates error under C++11:
error: non-constant-expression cannot be narrowed from type 'int' to 'double'.
In my opinion, this should be a warning, not an error, because it breaks
correct legacy code. The conversion from int to double is not in fact
narrowing, because there is no 32-bit integer value that cannot be represented
as a double.
