It really is a pity that Guix didn't go for Common Lisp instead — it does allow for gradual typing. And it has standardised a ton of stuff that Guile had to implement on an ad hoc basis.
Honestly, I kind of like how Guix and Guile have been growing together. Like Rust and Servo (and the Rust compiler), I think the constraint of having a general-purpose language, but a general purpose language that is also responsive to a bigger project, has been beneficial to both.
