Let's agree that serif fonts do not always carry boring stuff. And have a taste of it:

Programming languages should be designed not by piling feature on top of feature, but by removing the weaknesses and restrictions that make additional features appear necessary.

Otherwise said, Scheme offers a minimalist core of powerful primitives upon which one can build abstractions to solve (real world) problems.

The Scheme universe is vast and prolific. As programming languages, Scheme dialects target various niches and implement various paradigms. Some of them are part of the de facto standards (namely RnRS and SRFIs).

The best-known paradigm of agreed-upon practices revolve around Functional Programming.

Scheme might be a dynamically typed language, but it can compete with its scions and siblings when performance matters.

Few programming languages can compete with Scheme when it comes to computer science whether it is Programming Language Theory, or Artificial Intelligence.

That being said, Scheme implementations might be missing some love. That's a good opportunity for you to learn something useful and give something back.

Or, like others, to make it your secret weapon.
