I constantly need to use long class name like 

```
SomeReallyLongModuleName::AnotherLongModuleName::YetAnotherLongClassName

```

in the project. I want to access this class by something like `YALCN`. Where it's the best to keep definition like 

```
YALCN = SomeReallyLongModuleName::AnotherLongModuleName::YetAnotherLongClassName

```

And is it a common practice, or people constantly use fully-qualified long name?
