instead, why not just move the extensions namespace up here (and get rid of all
extensions:: prefixes)?

[Finnur, 2014/05/21 16:30:32]

See? You're not as dumb as I look! :)

nit: slightly more efficient:
registry->enabled_extensions().GetByID(extension_id);

Saves Registry from having to compare the mask.

inline.

[Finnur, 2014/05/21 16:30:32]

I find my way generally helps readability and avoids awkward line splits. The
compiler should optimize this out anyway, so the end result is the same. But
whatever... (shrug)

[Devlin, 2014/05/21 17:00:39]

If it's just one object, I find inline perfectly easy to read.  If it's
something like:
ExtensionSystem::Get(web_contents()->GetBrowserContext())
    ->extension_service()
    ->pending_extension_manager()
    ->GetPendingIdsForUpdateCheck(...);
I agree whole-heartedly that the extra pointer is worth the readability. :)
