Make the function from LowercaseLetter to UppercaseLetter type-safe, too. It might not make much sense in this scenario (there is no one-to-one mapping between upper- and lowercase…

Scala has 1., 2., 3., 4., 5. 6. seems to be a fix for an OCaml-specific issue. 7. is obsolete (imho), because with macros the most important benefit of decidable type systems (know…

Can you explain/give a link?

Go's GC is non-moving, exactly because they can't precisely know what a pointer is and what is just some random int. So it's basically as if all objects are pinned in Go. I don't e…

They could, but I expect their "worse is better" attitude will prevent it.

I guess it depends on where one comes from. If one compares Scala to Scheme, sure, Scheme is ridiculously simple compared to Scala. But if one compares Scala to languages which are…

While I can't speak of traction in enterprises in Germany, I wonder what the notion of "Scala with its everything and the kitchen sink feature set" is about. This seems to be a pop…

You can use any templating system you want, including the one which was used in Play 1.

As a general policy, if I spend time explaining things I require people to do some homework on their own. This way people who are lazy, whose interest is just strong enough to make…

Can you give some details what caused the issues in your the 2.9 -> 2.10 migration?

Ah right. I refactored the messages a bit and didn't completely update the post to mirror that.

C is easy as pie. It's the most fundamental language. Forth is a super-cool game. My kid already rocks on an HP-41 calculator (RPN). When I introduced him to Forth he literally sai…

I just fear this "it must stop breaking things after 1.0" attitude some people have. That's exactly what the death of a promising language looks like. Those people should just go e…

That has exactly been my experience, too. The people who think Go is great are the same who lack substantial experience with any remotely modern programming language.
