Hy
Hy made me reconsider Lisps and I'm glad it did. I'm now using CL quite a lot. It's possible to use Python libraries from CL:<p>- there is py4cl and async-process: <a href="https://github.com/CodyReichert/awesome-cl#python" rel="nofollow">https://github.com/CodyReichert/awesome-cl#python</a><p>- NumCL is a clone of Numpy: <a href="https://github.com/numcl/numcl" rel="nofollow">https://github.com/numcl/numcl</a><p>Common Lisp has many advantages though:<p>- you can build a self-contained binary of your app, including web app. It's such a breeze to deploy, and it's possible to ship a binary to users.<p>- the REPL is much better and more fun than ipython<p>- CL is compiled. We compile our code <i>function by function</i>, and we get many compiler warnings at compile time.<p>- CL is stable, the syntax is simple, you can add the syntax you want with extensions (decorators, string interpolation,…) and yet, the implementations keep improving, and new ones are created (Claps, CL on LLVM).<p>- CL is fast (how pgloader got rewritten from Python to CL: <a href="https://tapoueh.org/blog/2014/05/why-is-pgloader-so-much-faster/" rel="nofollow">https://tapoueh.org/blog/2014/05/why-is-pgloader-so-much-fas...</a>)<p>- there may be more libraries than you think: <a href="https://github.com/CodyReichert/awesome-cl" rel="nofollow">https://github.com/CodyReichert/awesome-cl</a><p>- the object system is very nice, the multiple dispatch makes me have a cleaner and shorter ABI of my app.<p>- there are more editors with good support than Emacs: Atom support is getting very good, and there's more: <a href="https://lispcookbook.github.io/cl-cookbook/editor-support.html" rel="nofollow">https://lispcookbook.github.io/cl-cookbook/editor-support.ht...</a><p>- the (default) package management system works with "distributions", à la apt/Debian, so it doesn't break suddenly because of a third party of a third party dependency.<p>Of course, the web stack is less mature (but more promising: see Weblocks <a href="http://40ants.com/weblocks/" rel="nofollow">http://40ants.com/weblocks/</a>) and CL might be more difficult. It's not for every one. But it's been a joy so far.
