-Common Lisp vs C/C++

-April implements the language and just punts to CL for all the I/O and system level stuff. Like it doesn't have to implement a REPL, or a line editor or APL workspace files/array stores.

Thanks. I'm guessing (based on my knowledge of J and all its optimizations/special forms) that Dyalog APL would still be more performant too? I didn't see it mentioned on the GH README.

Yes, the talk mentions that Dyalog is still much more performant, given how much time and effort has been spent on optimizing it.
