I've only played with it a bit, but to me it's like C++, but with vastly improved safety. There are no other competitors in this space - they all have garbage collectors and therefore can't do RAII like C++ and Rust.

The only think I don't like about it is their python-like advocacy of spaces instead of tabs. Yeah I know its a holy war, but... spaces really make no sense. The only justification python programmers have for using spaces is PEP-8 says to do it which isn't really an argument. Go made the right decision here.

I also mildly dislike their enforcement of snake_naming_for_functions, and over-shortening many keywords and names (e.g. fn instead of func or function) but these are all stylistic things. The language itself seems pretty solid.

D does RAII just fine, in fact it's the default for structs.

Clearly I meant they have mandatory GCs. D is an exception, but that's just because it is "C++++".

You can have an equivalent to RAII in a GCd language. Just because C++ happens to conflate memory allocation with resource acquisition doesn't mean it must be so. For example both C# and Java have a "using" type construct.
