Scala for .NET

now, some benchmarks ?

@blowdart: according to Miguel, "the much better Scala collections library would be the natural developer choice anyway." Not sure why they are much better, but the .net framework collections were always a little strange.

Maybe the "better" bit the Scala collections can be immutable.

Also can't Scala be generic on both parts  M<T> ,  T and the M,

Clearly Scala collections are better factored. Immutability/mutability is but one axis:

The following figure shows all collections in package scala.collection. These are all high-level abstract classes or traits, which generally have mutable as well as immutable implementations.

The following figure shows all collections in package scala.collection.immutable.

And the following figure shows all collections in package scala.collection.mutable.

(All three figures were generated by Matthias at decodified.com).

I don't know if Scala has something like LINQ though, in particular IQueryable. Apart from this, a prime concern would be performance.

the Traversable trait has many operations, similiar to LINQ.

the collections api was the major feature of Scala 2.8, very advanced stuff

and parallel collections was a major feature of Scala 2.9

@exoteric:, @felix9: I can see the scala collection design is much better than the .net collection design. Reminds me of the STL. When will .net developers get nice collections like that?
