Hi Namit, I like your proposal very much and I would take it a bit further:

I'm concerned that examples in the code (comments) might very quickly become obsolete as it can very easily happen that someone will change the code without changing the example. What about using for this purpose normal unit tests? Developers will still be able to see the expected input/output, but in addition we will have automatic way how to detect (possibly incompatible) changes. Please note that I'm not suggesting to abandon the *.q file tests, just to also include unit tests for complex methods.
