The same can happen with a simple abstract expression in native syntax (in fact tons of tools in all languages that do that). LINQ just gives you a standardized built-in DSL for that -- but nothing you can't build yourself with the language's main syntax. Heck, LISPs have
Okay so where is it? What language besides some .Net based languages allows me to take the same query expression and have it interpreted differently based on the provider and allows me to switch out an RDMS or Mongo for example without changing the calling code?half a century ago I wasn’t even born (about 5 years later). Saying Lisp did it 50 years ago is about like Mac users bragging in 2019 that they had a GUI before PCs.
As far as LISP, what are the job opportunities like in 2019?
Yes, they only made a dent with the smarter developers.
Can I make money with those languages?
Java has been fast for over 15 years now, so not sure what you're getting at here. Faster than C# as well, so there's that too.
Benchmarks?
