 Replying to [comment:5 westi]:
 > Switching to an Exception and throwing it changes the whole way in which
 we use WP_Error.

 Well actually prior to PHP 5 exceptions were not available but the
 suggestion given with the patch is not changing much so far, it's just
 extending the current.

 To have an WP based, throw-able error class. If you don't know what the
 benefit of a concrete exception class is, please let us know.

 >  * How is this backwards compatible with old code?

 I expect it to be 100% compatible. The WP_Error class can be instantiated
 as known and returned from functions. If you see some scenarios where this
 should not be the case, please report them in this ticket.
