    * CLOS being bolted on instead of truly integrated in the language; would need a JIT and something like https://github.com/marcoheisig/fast-generic-functions on system classes to go fast enough, Julia kinda does this (but it hurts my eyes)

    About static typing and generic functions, are there limitations to fast-generic-functions built over sealable-metaobjects too? I felt that reasonable, albeit it takes away the dynamic nature of the objects after sealing.

    And, there won't be a way to properly understand what exactly PF (or CL) misses without immersing myself into a ML-style something, is there? As in, I get some parts of what you are saying; I myself had to (ab)use deftype and gensym intern for another library for providing (limited) parametric types; but I also fail to see something seriously wrong with it, given that it plays nicely with cl:declare, cl:typep and cl:subtypep for the primitive use case of single value type checking, declaration and with some additional things (compiler)macro based optimization.

What are some alternatives?

When comparing fast-generic-functions and abstract-arrays you can also consider the following projects:

ctype - CL type system implementation

ccl - Clozure Common Lisp

lisp-interface-library - LIL: abstract interfaces and supporting concrete data-structures in Common Lisp

polymorphic-functions - A function type to dispatch on types instead of classes with partial support for dispatching on optional and keyword argument types.
