Then mathematical neatness became a goal and led to pruning some features from the core of the language.

— John McCarthy, History of Lisp

If you prefer programming languages with a tidy and tiny core, you're in for a treat. This article drills down to the singleton primitive at the heart of Raku's metamodel ("model of a model") of a model of computation ("how units of computations, memories, and communications are organized")¹.

The reason I've written this article

It began with u/faiface's reddit post/thread "I'm impressed with Raku"². One of their sentences in particular stood out for me:

Coalton: Why is the interop not easier, and why might it be necessary for Coalton to be an entire language in itself?

If you came here searching for the context in which some reddit comments were written, you might want to check out this previous version of the article.

Several blog posts have been written about Coalton, about how it can be useful and what it brings to the table. However, to me, it hasn’t been clear why Coalton is the way to solve the problems that it does solve. Isn’t a simpler solution possible without making a full embedded language, and giving users the cognitive overhead of thinking about interop between normal lisp and coalton?

I have been thinking about this for a while as one of my pasttimes, and below I’ll summarize the better reasons why coalton might be the way it is. Perhaps, I couldn’t se
