I'm not sure I'd call LINQ a precursor when LINQ itself was based on haskell's monadic list comprehensions.

monadic list comprehensions aren't quite the same thing as optics, however.

List comprehensions aren't quite the same thing; they are declarative but they describe an iterative method of creating lists through maps and filters, whereas optics are semantically oriented around traversals and projections.

The nice thing about comprehensions is that, depending upon how one looks at them, they can be declaratively defined yet iteratively implemented.

isn't that what I said?

Wikipedia claims there are LINQ implementations for Javascript/Typescript and for PHP (in addition to C#, of course).

These are really just simplified versions, though.
