There are easy ways to do some subset of what LINQ does in Java (using annotation processors), in Go (using generators), in Python (using double-underscore methods to capture all the operations the expression is working with at runtime, see SQLAlchemy) and in Ruby.

There isn't a seamless way to do what LINQ does in any of those languages. But if the runtime supports a LISP then you can do more than what LINQ does (Clojure for the JVM, something like zygomys for Go, Hy for Python, and ... well, Ruby for Ruby).
