Are there more up-to-date D template tutorials?

[thebluepandabear]

Hello,

The GitHub repo which helps introduce new users about D templates 
(https://github.com/PhilippeSigaud/D-templates-tutorial) seems to 
be quite outdated.

As a beginner to D I have been struggling to learn about D 
templates, I haven't been able to find any up-to-date D template 
resources so I can learn this concept, which sucks.

Is anyone on this forums aware of any up-to-date (preferably 
2019+) D template books/resources? I know C++ has many books on 
this topic, but less so for D.

Help would be appreciated.

Regards,
