Deployment of what? How would a compiler written in ABCL and delivered as Jar be more difficult to deploy???
Accessibility? For who? The people who actually can maintain a Common Lisp compiler are using mostly Lisp and share parts of their code. There is almost no Common Lisp compiler written not in Lisp. Part of the runtime system may be written in C, but much of the rest is Lisp and especially the compiler.
For example the compiler for ABCL running on top of the JVM is written in Lisp:
Lispers have a decidedly notorious reputation for wailing about the lack of respect their family of languages tends to get.
I say this as someone who is incredibly fond of hacking in Clojure and has spent a fair amount of time with a couple Scheme implementations.
Railing against someone else's work without providing cogent reasons for why their approach is inferior to what you have in mind doesn't do much for the community.
Not this community nor the Lisp community.
It's a lot easier to make a case from a business point of view for a lisp that can be deployed anywhere JVM is, rather than potentially have to get into the rigamarole of standardizing another piece of technology.
Programming languages that never help programmers get their jobs done don't help the world much beyond being proof-of-concepts.
That's my point and it's the point you need to refute before you start flailing around like a wanton child in retaliation.
When your language/toy of choice is unproven and not otherwise well accepted in the business/technology world the onus is upon you to prove your points.
No one owes you or your preferred tools any free credibility.
So much drivel, so little content. Stop writing bullshit.
ABCL is written in Lisp AND RUNS ON THE JVM. What's so difficult to understand? You can deploy it everywhere where the JVM runs. Totally painless.
All of Common Lisp has already been written in Lisp and is available both in GPL and Public Domain versions. A Lisp compiler could just reuse all of that or parts of it and just needs to compile to JVM byte codes. There is no need to rewrite all of that in Java - it exists already. There is no need to rewrite the library functions in Java. There is no need to rewrite the REPL in Java.
All you need is the code generator and some runtime parts. The rest, and that's a lot, exists already and can be taken.
The only thing you get by writing 100% Java is some Lisp dialect that will have tons of bugs and problems.
