Code golf can be fun, but I don't think it belongs on real projects.
These days it's rather rare for tricky code to be really necessary. Even for fairly high performance projects, compilers have become good at making optimizations. Also, often the hardest thing to achieve is to find the simplification that takes a problem which appears hard and makes it easy.
I imagine that there are still places where tricky code is needed for performance, but it must be a vanishingly small segment of the total software ecosystem...

We're a place where coders share, stay up-to-date and grow their careers.
