print line numbe

print line numbe

[Harry Putnam]

How can I make a piece of elisp report the line number when it prints
a message?

Something along the line of the __LINE__ operator in perl, 
or the $LINENO operator in shell-scripting.

Something like:

   (message "Hello from line: " something-that-reports-line-number)

(message  (format "Hello from line: %d" (line-number-at-pos)))

I thought he was asking for the line number of the message call in the .el,
not the position of point in the current buffer.

Something like __FILE__ and __LINE__ for Elisp would be nice to have.
