zkl is written in zkl. The compiler is big. The VM has a compiled (C) image of the compile as a big table, ie the system is image based. Here is an example of compiling and testing a new compiler:
<pre>
$ zkl --package Src/Compiler/compiler.zkl
Compiling asm
Compiling parser
Compiling tokenizer

Since the compiler is part of the VM, you can compile from the REPL:
<pre>
zkl: Compiler.Compiler.packageFile("compiler.zkl")
Compiling asm
Compiling parser
Compiling tokenizer
...
</pre>
