Using C# as an example, foreach and IEnumerable are baked into the language as is try/catch and more recently Async/Await. These are all just library functions in Haskell and often more general (e.g. forM in Haskell works for any Monad not just IO). Because they are library functions they can be changed/customized very easily. In C#, how could foreach be made to support a different stream type, exceptions be made checked or Async/Await be made to suspend across stack frames?
For this reason, Haskell is probably closer to a general purpose language than many of the imperative systems programming languages (especially Go).
C# has LINQ. Implement Select and SelectMany extension methods for whatever you like, and you can use the LINQ syntax with your type just as easily as with IEnumerable. Foreach and async/await are baked in, that's true, but the LINQ syntax is easily extendable to new use cases.
What we have done, and what the mathematicians call Monads, we have identified these sets of operations, we call them standard query operators; we have a list of about 25 standard operators that you can apply to any data model.
