ah, sorry, I misunderstood. It looks like you need to change the 
lin

auto sc = new SomeClass ();

to

auto sc = new SomeClass!BaseClass ();

The compiler complains because SomeClass is a template when you 
call SomeClass() without !() template parameters. It only becomes 
a type once instantiated with parameters.
