I grew up with the Icelandic layout. When I started programming professionally I taught myself the en-us layout and stared using that instead. It is much easier on my hands and fingers; it really does show that the people who came up with the syntax for most of the programming languages in use picked things that were easy to type on a US layout and didn't give any thought to the rest of us.

I’d love to know what the result might have been if they gave some thought to the rest of you. And if a person is designing a programming language syntax, I don’t see why keyboards that are foreign, even unknown, to them merit much consideration.

BTW I really don’t think the en-us layout is actually nice on hands and fingers. All the programming symbols are a stretch. I now use Karabiner to make easy key-chords for all the symbols, e.g. f-j is ( and f-k is ).

I do not think there's a particularly feasible way to facilitate every keyboard layout out there, so it makes sense that they are at least built with one keyboard layout in mind, much like I think it makes sense that programming in general is overwhelmingly done in English. It increases interoperability significantly.

I tried that once, but already back then my muscle memory wasn't having it. Now I'm too old to put down the required hours to relearn and get back up to speed.
