Any benchmarks? I have a combinatorial enumeration comparison project where the .NET jit optimized my hot loops for F# to in some cases matching Rust performance. F# is inspired by OCaml, and for me F# runs twice as fast.
Scala got a face lift where indentation replaces syntax, a modern poetry look many of us can't live without. It is entirely practical to eliminate most parentheses from Lisp (I have written thousands of lines of Scheme this way, hands down my favorite code to read), but doing so will lead to a tribal swarm attack. It is also easy to train Common Lisp to lay off the caps, but any stock installation greets users with an old man shouting (GET OFF (MY LAWN)).
The idea of Lisp is pure genius. One wonders where we would be today if any Lisp took a more pragmatic attitude towards encouraging adoption.
I feel CLISP is pragmatic (it’s both low level and high level, multi purpose, has a formal specification, is a standard), but the world just changed too much around it.
Have you tried Clojure?

If Dotcl does have good performance, it would be interesting to try running Coalton on top of it too. Coalton syntax is probably not unusual if you are familiar with OCaml and F#: https://github.com/coalton-lang/coalton (Though I'd expect the performance of the typical use case of running on top of SBCL to still be better.)
From the same project there's the recently released mine editor that's trying to be a friendlier gateway into trying Common Lisp (and/or Coalton) than emacs: https://coalton-lang.github.io/mine/ Time-to-first-SHOUTING is still once you start a REPL though -- it tells you that your package (namespace) is CL-USER. I sort of think it's one of those things that grows on you, or at least isn't annoying after a while (until you need to deal with certain foreign function interfaces anyway), and it's an interesting possible convention to use SHOUT-CASE in docstrings to call out specific parameters or other function names instead of some @param, \param, @link, or what have you.
