    Note that an exception's properties are populated when the exception is *created*, not when it is thrown.  Throwing the exception does not seem to modify them.

    Among other things, this means:

    * The exception will blame the line that created it, not the line that threw it.

    * Unlike in some other languages, rethrowing an exception doesn't muck up the trace.

    * A thrown exception and an unthrown one look basically identical.  On my machine, the only visible difference is that a thrown exception has an `xdebug_message` property while an unthrown one doesn't.  Of course, if you don't have xdebug installed, you won't even get that.

    Note: this documentation not full, ReflectionObject::export($exception):
