Re: Why function gives this error?.. "Wrong type argument: stringp, #<buffer *Messages*>"

Hi Chris,

(buffer-list) does not evaluate into a list of strings like you expect it
evaluates into a list of buffer objects and these can not be compred with
your comparison function string<. I expect that if you debug your code you
find that the string< function emits the error message.
