We need a way to programmatically tell if we are in a sidebar

[jorbin]

There is currently no way to tell if you are in_a_sidebar or doing a widget which makes me a sad stallman lookalike.

Sounds like a reasonable request.

I'm not sure what you're trying to do, but you might be able to accomplish it by attaching a callback to the 'dynamic_sidebar' action hook.

That doesn't tell him that he's in a sidebar — just that one started. There is no hook that fires when the sidebar is done.

I'm not saying we shouldn't add some more action hooks; inside-widgets-sidebars.php is just for fun to see if it could be done with the current code.
