I did just such a thing the other day out of curiosity: http://pages.cs.wisc.edu/~psilord/blog/31.html It probably has some wrong edge conditions concerning the C code emission because I didn't really clarify the distinction between evaluating a function call into an C expression or a C statement, but for a few hours of hacking it provided a lot of enjoyment. I'm doing a bunch of experimentation with writing a compiler in Common Lisp, so I have several of these types of hacks. Another one is converting a very tiny subset of common lisp directly into three address code. Stuff like that. Lisp is pretty awesome for writing a compiler... -pete

If you found those "irrelevant and unbeneficial", then while I agree that he may have been wasting his time, he would have been wasting it even worse trying to walk you through the technical material when you're clearly not currently at a stage where you are ready to learn anyway. > Now, I find out > from you that he has/had a business concern or interest in a company > that is writing/wrote lisp interpreter in C.

If you are trying to imply that he was acting in some unethical way, you have further cemented the notion that trying to talk to you is a waste of anyone's time. *plonk* -s -- Copyright 2010, all wrongs reversed.

Unfortunately many so-called experts in the field look down on newbies and mistreat them (in any programming language forum), forgetting in the process that they were also at a certain time newbies until someone gentle and nice enough teachers took the trouble to educate them. On the other hand there are less neurotic experts out there who are glad to help out someone learning. It's like in some universities, you have the bad "professors" who are freaks (probably they have a lot of problems at home, their wives screwing all the males on the block, daughters drug addicts etc) and want to take their hatred out on you, and you have the good and mentally stable professors who actually deserve their title. |
