The F# folks (including Don Syme) did a fantastic job on the early versions of the language (I used it up to ver 2 or early 3), but I am tired of the corporate engine that funds that ecosystem. I now construct my software within an operating system of a different pedigree. Such considerations are important to me, but thanks for sharing your preference. As for me, I hate nothing or no one, but I am as picky as a poor man can be about whom I choose to rely on for my tools.
As for your opinion on the borderlands of mental illness, I'll contact you at your outlook email address should I seek your opinion about such differently-technical topics. But I was only asking if the OCaml compiler can target specific varieties of ints, as the .NET compiler does.
Other options have worse support and weaker tooling, and often not even more open development process (e.g. you can see and contribute to ongoing F# work on Github).
This tired opinion ".net bad because microsoft bad" has zero practical relevance to actually using C# itself and even more so F# and it honestly needs to die out because it borders on mental illness. You can hate microsoft products, I do so too, and still judge a particular piece of techology and the people that work on it on their merits.
