Whether a conversion is or is not narrowing, and whether narrowing is permitted
or ill-formed, is specified by the C++ standard. You're not alone in finding it
both to be inconsistent and to reject completely reasonable code; that's why
Clang provides a flag to turn off the error.
For a description of the rules, see the standard text at
<a href="http://eel.is/c++draft/dcl.init.list#7">http://eel.is/c++draft/dcl.init.list#7</a> or the explanation at
