When I made partcl, I also wrote a brief post of why+how I implemented it: http://zserge.com/blog/tcl-interpreter.html http://zserge.com/blog/tcl-interpreter.html I tried to keep data representation separate from the main interpreter code, so if one needs to use binary data or real lists - he may only rewrite a small part of code.
