So this was invalid. Also the new alias syntax allows aliasing a function type:

// old
alias extern(Windows) HRESULT fnNtQuerySystemInformation( uint
SystemInformationClass, void* info, uint infoLength, uint* ReturnLength )
nothrow;
// new
alias fnNtQuerySystemInformation = extern(Windows) HRESULT(uint
SystemInformationClass, void* info, uint infoLength, uint* ReturnLength)
nothrow;
