How to iterate through all modules for use with the new getUnitTests trait?

[Gary Willoughby]

foreach (module_; ModuleInfo)
{
     auto func = module_.unitTest;
     func(); // run tests;
}

The above code retrieves all of the current project's modules and 
then grabs each module's unit test blocks. The only trouble is 
that the module's unit tests are kinda rolled into one function 
as show by the 'func' variable above. It would be nice to do this 
but get each individual unit test instead of dealing with these 
rolled up versions.
