    comphelper: Allow initializer lists for Sequences of NamedValues.
    
    This is particularly useful for creation of sequences that are later
    unwrapped using comphelper::SequenceAsHashMap.
    
    Eg.
    
        uno::Sequence<uno::Any> aArguments(comphelper::InitAnySequence(
        {
            {"SomethingNamed", uno::makeAny(true)},
        }));
    
        Reference<XExporter> xExporter(aFactory->createInstanceWithArguments(..., aArguments), UNO_QUERY);
    
    and in the implementation where the arguments are consumed:
    
        comphelper::SequenceAsHashMap aArgumentsMap(rArguments);
        mbSomething = aArgumentsMap.getUnpackedValueOrDefault("SomethingNamed", false);
