Thank you!

Somehow I missed the 'Advanced features' link, which was exactly what I 
was looking for.

I did not know about Fusion either, but for what I need it looks 
complicated. :) Anyway I find that when using tuples heavily it is 
actually better to define classes/structs for your data, as using 
t.get<idxHostname>() all the time is no better than t.hostname, and also 
not clearer.
