Thank you. 
It seemed like little a riddle!!  Evaluate a variable that has function
in its name. 

But how do we use scratch a classic REPL ? I mean if a was in a clisp
repl it may had occured me to 'evaluate' a variable. But by default
scratch is not a repl. 
I indeed evaluated as you said auto-fill-function but i get my result
in the echo area.

Also how evaluating a variable in scratch the scratch nows for which
buffer we asked for ?
