The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Eliminating CLOS for a 4.5x speedup
I wonder if things like https://github.com/marcoheisig/sealable-metaobjects would help with the speed while keeping the CLOSiness.

Common Lisp polymorphic stories.
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.

Adding new types and operators to Lisp
If performance is a concern, then you would want to stick to CLHS provided simple-array and create appropriate types using deftype, and then dispatch on the types either by yourself, or by using something like polymorphic-functions and polymorph.maths.

defgeneric and &rest
If you want to dispatch on vectors, you can try out polymorphic-functions which was made for the express purpose of dispatching on specialized arrays aka types rather than classes.

numericals - Performance of NumPy with the goodness of Common Lisp
Since the past year or two, I have been working on numericals that aims to provide the speed of NumPy with the goodness of Common Lisp. In particular, this includes the use of dynamic variables, restarts, and compiler-notes wherever appropriate. It uses CLTL2 API (and may be slightly more) under the hood to provide AOT dispatch, but nothing stops you from combining it with JAOT dispatch provided by numcl/specialized-function. This also spawned a number of projects most notably polymorphic-functions to dispatch on types instead of classes and extensible-compound-types that allows one to define user defined compound types (beyond just the type-aliases enabled by deftype. Fortunately enough, interoperation between magicl, numcl and numericals/dense-numericals actually looks plausible!

Before reading this, please go and check out https://github.com/digikar99/polymorphic-functions which this project is fully based on. It's great.

polymorphic-functions - Possibly AOT dispatch on argument types with support for optional and keyword argument dispatch
What I am calling parametric polymorphism is this test:
What are some alternatives?
When comparing sealable-metaobjects and polymorphic-functions you can also consider the following projects:
ctype - CL type system implementation
lisp-interface-library - LIL: abstract interfaces and supporting concrete data-structures in Common Lisp
fast-generic-functions - Seal your generic functions for an extra boost in performance.
ccl - Clozure Common Lisp
cl-parametric-types - (BETA) C++-style templates for Common Lisp
cffi - The Common Foreign Function Interface
numericals - CFFI enabled SIMD powered simple-math numerical operations on arrays for Common Lisp [still experimental]
coalton - Coalton is an efficient, statically typed functional programming language that supercharges Common Lisp.
dense-arrays - Numpy like array object for common lisp
