Of course, there can be no objective measure easily made, and I do not want to engage in language wars.
That said, I am a C++ expert, but contend that each of Lisp, Haskell, and Scala are far deeper languages, with more involved in their mastery than C++.
No, UncleOxidant, it is definitely not "especially true for C++". There are plenty of powerful languages out there, many with more subtleties than C++, and longer roads to mastery.
No one disputes that C++ has a long road to mastery, but there are plenty of other languages for which that is true. So, C++ is not special in that way.
kailoa makes a good point: removing keywords from the job posting risks not appearing in a potential employee's search.
I think that the trick is to have "just the right" keywords, and no more. The particular example that I give in the article has too many. So, fewer is better, in that case.
Thanks. I thought that someone was suggesting that they were using let = ... syntax. Now, I understand that the idiom you showed is "let binding" in the Javascript world.
