Question

This is something which has been bugging me with the Google Chrome debugger and I was wondering if there was a way to solve it.

I\'m working on a large Javascript ap

Based on the answer of @josh, this prints in a console REPL, shows in console.log and shows in the debugger tooltip:

var fn = function() { 
   return 1917; 
};
fn.oldToString = fn.toString; 
fn.toString = function() { 
   return "That fine function I wrote recently: " + this.oldToString(); 
};
var that = fn;
console.log(that);

Inclusion of fn.oldToString() is a magic which makes it work. If I exclude it, nothing works any more.
