For example, I'm writing a lot of queries by hands...
This functionality is available in many languages and it's just convenient. Of
course it is possible and without it, but why?New symbols increase a complexity of our code and our documentation.If some functionality can be implemented via functions without performance impacts, we should not to create new operators or syntax - mainly for corner use cases.
I can understand, so current system of accessing array data has some disadvantage - the behave was designed twenty years ago, when the arrays didn't support NULLs, but I am not sure, if introduction secondary accessing system helps. Probably not.
