For me the most welcome change is the vastly improved consistency of the Seq/List/Array APIs.
This is now fixed. Although there is not yet support for creating and manipulating high-rank arrays, the compiler will now properly handle these types up to rank-32."
Has anyone here ever used "high-rank" arrays? The deepest I've ever gone was 4 for a lookup table, but I'm wondering what the use-case is for super high depth arrays as well as why there is a limit at all.
The main reason for the fix was because F# pre-4.0 can't reference overloaded methods where one or more of the overloads has one or more parameters which is an array of rank 5 or more. I had a 3rd party DLL I wanted to reference, where a class had generic overloads for all of the array ranks, e.g.,:
MyClass.Foo(T[])
MyClass.Foo(T[,])
...
MyClass.Foo(T[,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,])
I'm not planning to use such arrays any time soon, but I wanted to make sure that if other code was using these arrays I could reference it from F#.
