> Can you expand on Pascal vs Go? What is Go missing?
Pjmlp mentioned a few, though i wouldn't say so much they are things "Go is missing" but more "Go does not provide them" - at least in my mind it is more of a FPC has "more stuff you could use" than Go lacking stuff.

It is pretty much the same as you'd find in most other languages: done via threads with some language support for thread level storage. There are some helpers in the library and Lazarus also comes with a package that allows you to run stuff in parallel like a "parallel for", but nothing higher level than that.

I think if you want to make a desktop application that runs in multiple desktop OSes, it is worth to learn it so you can use Lazarus. For other stuff, i dont think it provides that much of a benefit compared to other languages. I think the weakest aspect might be server-side apps - there is some support (even out of the box and Lazarus even has some RAD support for it so you can do things like routing URLs to different parts visually) and a framework or two, but i get the impression that most effort is in desktop stuff.
