Tango-D2

Everything on dlang.org is fine. The phobos/ and library/ sections are two versions of the same content, generated from the same source files at the same time. The library/ stuff is the future, but not completely polished yet. The obsolete stuff is dsource.org. Most of it does not compile anymore and has no maintainers. If you are looking for libraries to use, go to https://code.dlang.org/. Phobos is the standard library. Tango is a D1 projects. Most of it has been ported and integrated into Phobos now. Some people still like the Tango XML library: https://github.com/SiegeLord/Tango-D2

Fixed with D2. Although, not all of Tango (the non-standard one) is available in D2/Phobos already. For example, Phobos has XML [2,3] stuff, but Tango's is supposed to be better [0]. Port is ongoing [1]. [0] http://dotnot.org/blog/archives/2008/03/12/why-is-dtango-so-...

I'm curious what the "few other things" are because the things you mention specifically are a few years out of date at this point. I'm not sure what licensing issues you've had but phobos is Boost licensed which is extremely liberal (basically "use for whatever you want just don't remove this license text when copying this source code"). Pretty much everyone uses D2 these days unless they are maintaining a legacy system written in D1 and transitioning to D2 isn't worth the effort in their case. Phobos versus Tango hasn't been an issue for years. In fact, in D2 you can use Phobos and Tango side by side[1]. Rust is very interesting and I'm excited to see where it is headed but it's still rather immature compared to something like D. 1. https://github.com/SiegeLord/Tango-D2
