Here's certainly a different take on language design:

I'm not convinced. All my engineering experience supports the idea that 
the larger the project and the more people are involved in it, the 
better off you are with isolation between modules and better enforcement 
of interfaces.

Simply relying on programmers being responsible isn't good enough when 
you've got a high risk application.

What are your experiences?
