Created attachment 139856 [details] Screenshot of Firebug's Labeling Eval'd scripts are currently labeled as (program). It's nice that we can access them, but the label is not especially handy. Firebug labels them with the name of the script performing the eval, and applying a sequence number. There's probably a better way, but it's a start.
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.
