Template Mixins

Explore how template mixins enable the insertion of template-generated code directly into D source files. Understand their use for flexible code reuse, how to handle necessary local imports, and how to identify the type mixing in the code to create efficient and maintainable D programs.

We'll cover the following...

Mixins are for mixing generated code into the source code. The mixed-in code may be generated as a template instance or a string.
