I disagree. Rather than coding for the benefit of someone who doesn't know the language very well - people should learn the language. If the company is hiring maintenance programmers who don't know what lambdas are - again, their problem.

I feel like we should have higher standards, and use the abstractions available to us grow the code towards the problem. Instead I see people writing long sprawling application that use the same low level library routines everywhere.

Maybe it's a quantity vs quality thing. And quantity is much harder to hire for, so my ideas lose out.
