Could you say 'Unix' in Ada?

Leaky Abstractions

What you are argueing is that Unix is full of leaky abstractions instead of sound design principles, so a largely unsafe systems programming language should be used to write application software.

I think you are very wrong.

Unix promotes enforced isolation of components (strong process isolation, multiprocessing over multithreading, piping smaller programs together to accomplish larger tasks) using well-defined interfaces. This principle actually matches much better with OO languages like C++ and Java than it does to C. C does very little to encourage much less enforce isolation of intra-process components except for along well defined interfaces.

In fact, it could be argued that Unix evolved the way that it did largely because C is so inconsistent with Unix's over-arching design principles. But then it is surprising that there aren't more microkernel based Unices.
