Agreed here as well.

I think that the different intentions of

1) lookup by interface in registry and

2) adaptation

will be easier to understand if the code patterns are different as well.



Because I doubt tuple adaptation is that frequent, I am for

where the something else is 'Interface.getUtility()'.

This way we can

- make the interface more prominent when doing lookups (and have some 
sort of symmetry between lookup and adaptation)

- and simultaneously keep the semantic difference between adaptation and 
lookup.
