prog langs

Systems:
Go
Rust

JVM:
Kotlin
Ceylon

Erlang VM:
Elixir

You need to benchmark Forth, but I doubt it will be faster than SBCL. Lua and Perl are out from the CPU cycle race.

Fortan, little to no functions/modularity, parsing, and above all morphing. You get no DSL out of it. For everything else, perfect. I would do my calculations it again, but I already have Haskell and SBCL for that. Ada if I want to sell to companies for compliance.
