If you just want to do low-level coding in a language other than those, the Free Pascal project (http://www.freepascal.org/) is very much alive, and very much none of the above. It's a nice, low-level language that also has a very nice, .NET-like object system if you want to reach for it. (In fact, the object system it has, modeled on Delphi's, was the inspiration for .NET's system.)
(Note that both the Free Pascal project and its sister project, Lazarus, have horrid websites that are not reflective of the activity or quality of either product. In fact, the top post on the Lazarus website right now is about how they need to fix the website.)
It's a shame Google could not have used FreePascal as the basis for Go, instead of thinking that C-like structure had to be forced into the syntax somehow "because it's familiar", even though Go clearly wants to be an extension of Modula, and often must break away from C practices that just don't work.
Given that the language was created by ex-Bell-Labs researchers (Ken Thompson, Robe Pike, Russ Cox and perhaps others), it is not surprising that the language was modeled after C.
Overall the current popularity of C (in systems software) gives an advantage to any language with similar syntax and semantics.
Yeah, they ganged up on the Swiss (U of Zurich) guy in the group, I guess (the guy that worked on the JIT at Sun who also worked on Go).
God I wish K&R layout would just up and die already, at least in terms of having function headers that span multiple screen widths. Personally, I like having "end" keywords, and a bit more freedom in the layout. (mostly, I like to be able to write one formal parameter per line in a function heading, and to use "Whitesmiths" layout vs K&R)
Go feels much more like Pascal semantically than it does like C. I wonder if there is any research to back up the decision to make Go look sorta, kinda, like C, or if it was all ego and/or inertia.
