So I think this is the answer: C++11 only as soon Windows guys will support 
it.

I also agree that we should allow & use C++11 as soon it wouldn't raise the 
bar for compiling Amarok from source. (which seems to be by the time when more 
projects start to use Qt5) Do we know other OSS projects starting to require 
C++11?

Another (and IMO important) benefit of C++11 is make-coding-fun one. Trying new 
things is fun and C++11 is sexy, perhaps Markey would enjoy coding on Amarok 
much more if he could use C++11.

This change doesn't really need a lambda support at all, just deduplicate the 
code into a helper function, it is only slightly less elegant. Please do it.

On the other hand, you haven't use all the power of lambdas - you wouldn't 
need to provide "wiki" as an argument, but instead use a closure to catch it 
directly in the lambda definition.
