> myriad reasons why Common Lisp is far superior to Clojure Some narrow view. Have you tried thinking that maybe Clojure intentionally chose not to include type declarations because they can lead to a messy middle ground? After all, maybe not every feature from Common Lisp needs to be replicated in every Lisp dialect? Besides, Clojure's Spec and Malli can be far more powerful for validation as they can define complex data structures, you can generate test data from them, you can validate entire system states, and they can be manipulated as data themselves. If CL so "far superior" like you say, why then it can't be 'hosted' like Clojure? Why Clojure has Clojurescript, ClojureCLR, ClojureDart, babashka, nbb, sci, etc.? I'm not saying that to argue your specific point. Neither of them is 'superior' to another. They both have different purposes, philosophies, and use cases. Each has its strengths, pros, and cons. And that is actually very cool. |
What? Type declarations in CL (which came from prior Lisp dialects) were added, so that optimizing Lisp compilers can use those to create fast machine code on typical CPUs (various CISC and RISC processors). Several optimizing compilers have been written, taking advantage of that feature. The compiler of SBCL would be an example. SBCL (and CMUCL before that) also uses type declarations as assertions. So, both the SBCL runtime and the SBCL compiler use type declarations.

ABCL does not exist?
