Rust's website is really good

I saw it via Reddit. Since the dlang.org website has been under discussion on this forum, I thought I would bring it up: https://www.rust-lang.org/faq.html https://www.rust-lang.org/ I admire the clean, modern look, simple colours and focus on what's important. The content is very good and

Using std.conv.to with std.typecons.Typedef

I am trying to create 2 types which contain integral values but should not be compatible with each other. std.typecons.Typedef seems perfect for this: alias QuestionId = Typedef!(long, long.init, "QuestionId"); alias StudentId = Typedef!(long, long.init, "StudentId"); However I'm failing to

[your code here]

The D code part on the front page has only 2 examples currently. I thought we should add to that. As per the instructions, I'm posting one sample here for approval: // Find anagrams of words void main() { import std.stdio, std.algorithm; string[][string] anagram_info;
