Examples block

[Engine Machine via Digitalmars-d]

We have a unittest, what about an examples?

Examples are self contained short programs, each block acts as a 
"main" function. One can run all the examples and spit out all 
the output consecutively. It also allows for more robust testing 
since it adds another layer.

It would provide better examples for docs also. Instead of using 
assert to assert stuff we can see a real program in action. The 
output of the example could easily be generated and added to the 
end of the code.

Seems like a win win! (maybe examples is not a good keyword, but 
that is moot)
