Except real people mostly don’t behave like this.
IMHO
May be you are right.
But for me a language is like a tool. if I have a task I will take appropriate tool whether it is pliers or a screwdriver it depends on a task.
I just have noticed that it may be impossible to make a good\simple hammer from pliers.
If you really enjoy such things ok, just do it.
But I think
if a pro does such things it can be very beautiful. But when you teach such things students it can be the way to really big dissapointments.
I have seen many such disappointments.
I do not think such simplicity is very good, but if somebody like it it is not my deal after all.
What I really dream about it is a mode which allow to write right scripts in scala.
- When you just do not need a build system at all
- where there are no binary incompatibility problem.
- When a single error in some unimportant file do not stop compilation at all.
- when you can simply call a method to usual scala code
It is a real key to simplicity 
(when all you need is vi editor and installed package)
it would be cool if there were a real simple scripts. There were a real big communities on such tasks and so on.
