I think it follows logically from the syntax of one level of backquotes. The inner backquote expands, producing a call to `cons' or `list' which contants comma-expressions; then the outer backquote expands them. I too found it hard to understand, and perhaps the code should be rewritten to avoid nested backquotes, for simplicity. But it is valid. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.
