Here’s a great, two part, video by Matthew Flatt about embedding DSLs in Racket. Being able to hack the language is one of Racket’s/Lisp’s killer features:

The End of Moore’s Law

For the last few years (since 2009), I’ve been pitching the idea to my peers that language speed & concurrency/parallel capabilities will become more important as CPU clock speeds plateau and manufacturers add more CPU cores instead of advancing clock rates. My 2+ year old Macbook Pro has 4 cores and 8 hyperthreads.

Update 11/23/2020: The ultimate winner for my primary programming language was Racket.

Background

The 2008 Programming Language Plan didn’t go as well as I hoped, so I’m regrouping for another go at it. I did make progress learning some Logo and teaching it to my daughters, and I worked through seven chapters of “Programming in Haskell” which was very enjoyable, but I also spent way too much time trying to decide which language(s) to learn without actually learning them.

This has been a long time in coming. Paul Graham and Robert Morris have released an initial version of the Arc programming language.
