Yes, exactly. If you override RTInfo in druntime I think it will work 
automatically. Currently RTInfo looks like this:

template RTInfo(T)
{
     enum RTInfo = null;
}

Override it to look like this:

template RTInfo(T)
{
     enum RTInfo = checkVirtual!(T);
}

If this doesn't work you could create a tool which imports all modules 
in the source code and calls the function for all modules.
