FAQ and explode/ implode

[Josh Gardner]

Q: Is it appropriate to send mail to comp.lang.lisp asking for help
     with Lisp homework?

  A: In general, no.
 

Sorry! But thanks for setting me straight on this.

     The only circumstance in which you should ever even consider
     sending mail to comp.lang.lisp or another public forum asking
     for help is where you have (a) identified in the post that
     you are asking for help with homework, (b) included a partial
     result as proof you have made an attempt on your own, and
     (c) exhausted all other avenues for getting help through your
     school, class, instructor, etc.
 

Well, I did identify part (a), and as for b and c, I spent time working out my own solution. In retrospect, I should have inculded in my original posting that I was merely looking for some ideas on how to write
implode and explode, and not a complete solution. So, I duly apologize to anyone I may have inconvenienced, offended, etc. Hindsight is always 20/20.

Thanks to those who gave examples illustrating use of coerce, becuase I was trying to use concatenate-strings, and it wasn't working like I hoped.
