When a console.log fires or an Exception occurs, you see the output in the console, and a linked reference to the script-name: line-number where the call was made. That's quite handy for digging through a large-code base. When you type a function name into the console, it prints out the function body. That's quite handy for small-functions, so you can remember what they are up to. Now, what about larger functions, or small functions that are a part of a class? It'd be handy to see those in context, with some syntax-highlighting. It would be fantastic, to see a linked reference to the funciton definition when printing out a function body in the console. Not sure how difficult that would be, but it would be handy.
Closing as invalid, as this bug pertains to the old inspector UI and/or its tests. Please file a new bug (https://www.webkit.org/new-inspector-bug) if the bug/feature/issue is still relevant to WebKit trunk.
