QStringLiteral does not work with MSVC2010

QStringLiteral has several problems on msvc2010

I.

    // ok
    QString s = QLatin1String(
        "hello"
        "world");

    // fail
    QString t = QStringLiteral(
        "hello"
        "world");

.\main.cpp(27) : error C2308: concatenating mismatched strings
Concatenating wide "hello" with narrow "world"
.\main.cpp(27) : error C2308: concatenating mismatched strings
Concatenating wide "hello" with narrow "world"
.\main.cpp(27) : error C2308: concatenating mismatched strings
Concatenating wide "hello" with narrow "world"
.\main.cpp(27) : error C2308: concatenating mismatched strings
Concatenating wide "hello" with narrow "world"
mainwindow.cpp

There is known workaround, use

 QStringLiteral("\
hello\
cruel\
world"); 

instead;

II.

 
QString names[] = { QStringLiteral("hello"), QStringLiteral("world") }; 

in global scope it fails with:

.\main.cpp(12) : fatal error C1506: unrecoverable block scoping error

in local scope it fails with an internal compiler error.

III.

template <typename T> struct MyTrait { static QString name; };
template <> QString MyTrait<int>::name = QStringLiteral("int");

.\main.cpp(10) : error C2332: 'enum' : missing tag name
.\main.cpp(10) : error C2065: 'Size' : undeclared identifier
