The Great Ideas of the Software World, or the Lessons Learned in Software

1. Domain-specific languages should be embedded. In practice, this means that you should be able to, either: have code written in a DSL inside of a non-DSL code, or, equivalently, be able to write and invoke non-DSL code in a file with DSL code.
   • Good: regular expressions, xpath, CSS-in-JS, Racket/Scribble, ...
   • Bad: plain CSS, SASS, LESS; Jinja2 [1]
2. Gradual Typing is the Right Way (TM)

Footnotes

1. Only partially true, because you can actually access arbitrary Python functions out Jinja2 as described here.
