Indeed, just as functional interfaces are "nominal function types", 
records are "nominal tuples".  And as lambdas can be considered literals 
for functional interfaces, one could _imagine_ a similar conversion for 
records.

But, before we close down this thread, I just want to clarify that Remi 
meant "one can write" as leaning on that imagination -- that it was 
imaginable that, in some future language, such a conversion is possible 
-- not that this is currently on the plan.
