OK, so since I've never actually bothered to look at what LINQ actually is.. there may be others in the same boat: "LINQ allows you to query any enumerable collections such as List<T>, Array, or Dictionary<TKey,TValue>.". Got to admit I still find the LINQ to DB passtru rather opaque even after reading up on it: https://stackoverflow.com/questions/30716776/passing-a-query...

Basically allowing for a uniform way to query data which is reminiscent of a more modern version of SQL (in my optics anyway). Does anything library wise come close to this within the Golang ecosystem?

While LINQ does include a library of extension methods for functional programming with .NET collections (which is great), it also includes "Expression Classes". In a nutshell, this allows a user to pass a single expression lambda to a function, and the function implementor receives the abstract syntax tree for the lambda, not the lambda itself. You can then not only receive and analyze these trees, you can also manually build and compile them. This effectively allows a limited set of runtime macros within .NET.
