> Still, the basic eval command looks remarkably similar in lisp vs TCL. The primary difference is whether arguments are evaluated before (Scheme/Lisp) or after (Tcl) being sent to the function/command. The deferred evaluation is what allows you to do things that you need macros for in other languages. (ie. you need deferred evaluation or macros to implement short-circuit operators, for example) However, early Lisps had FEXPRs which also deferred evaluation. The late John Shutt built and entire Lisp called "Kernel" around the idea: http://web.cs.wpi.edu/~jshutt/kernel.html I strongly recommend a read through his PhD thesis: https://www.wpi.edu/Pubs/ETD/Available/etd-090110-124904/ Unfortunately, his implementation isn't anywhere near as good as his conception. Other people have implemented it better. http://axisofeval.blogspot.com/sear
