Hey i can do that in $php too!

    function execute($order, $callbacks){
        foreach($order as $i){
            $callbacks[$i]();
        }
    }

    function abcProcs(){
        foreach(func_get_args() as $f){
            eval("function $f() { echo '$f'; };");
        }
    }

    abcProcs("A","B","C");
    execute([0,0,1,2,1,2], ['A','B','C']);

edit:

you don't have to quote the function names (just to show they are really functions and not closures):

    execute([0,0,1,2,1,2], [A,B,C]);

Most scripting languages have miserable performance characteristics and lack native types. The beauty of Nim is it isn't a scripting language, it just looks like it is.

Nim isn't C/C++, but it performs like it is C/C++. Nim isn't Golang, either, but it compiles programs like Go does, down to a self-contained binary with no dependencies. You can even statically link a Nim program against musl libc to ship without even a dependency on glibc.

This puts a completely new spin on writing performant code - just skip the C and write your code in pure Nim. It's a lot like writing Python except you produce comparable results to what you would get from writing your code in C or Go.
