If it's been more than a few years since you've evaluated D you might want to check it out again, it may be worth your time. D is a language I knew about for years, and recently is where I've come to appreciate it for it's many features. D has things like array slicing, [OPTIONAL] Garbage Collection, an amazing Web Framework called Vibe.d with it's own template engine called Diet-: http://vibed.org/ https://vibed.org/blog/posts/introducing-diet-ng Things I like is Vibe.d is not just a Web Framework but a full networking stack too, also it supports Pug / Jade like templates (see Diet-NG) you make and compiles them when you compile your project, so your website runs off a native executable using fibers instead of threads. Vibe.d is undergoing a period where the core is being rewritten to where it is more compartmentalized so that you pick and choose which parts you need, MongoDB, PostgreSQL, layout engine and other goodies, there's even a templating library whose syntax is based around eRuby called Temple (though the syntax can be tweaked) that supports Vibe.d: https://github.com/dymk/temple
