LINQ is so fucking useful and well designed feature of .NET ecosystem that it is unreal when you gotta use lang which doesnt have such a thing.

C# design team is/was unparalleled

LINQ is a veritable footgun in any large team I find. While it's extremely powerful and really nice, it's so so so easy to blow your toes off if you don't know what you are doing. Some of my favourite screw ups I saw:

* Not understanding when something is evaluated.

* Not understanding the computational complexity of multiple chained operations/aggregates.

* Not understanding the expectation that Single() requires exactly one of something.

* Not understanding how damn hard it is to test LINQ stuff.

How much of that is LINQ-specific and how much is just the cost of using an ORM to build queries rather than typing them out as SQL?

I've never encountered testing problems with LINQ-to-objects.
