For those who haven't heard yet, F# is joining the "official" .NET language family. As Soma says, "[t]his is one of the best things that has happened at Microsoft since we created Microsoft Research over 15 years ago." I am just as excited as he is. A huge congrats to Don. He's been working super hard to build and evangelize F# for several years now, and getting the attention of a huge division like DevDiv isn't an easy thing, but in the end sanity does prevail. As a blanket statement, the more functional .NET programmers' brains become, the more latent parallelism the programs they write will contain.
