I find this really interesting from the perspective of programming languages.

The languages that add on information not required in English reminds me of type declaration for variables versus languages where you don't have to declare a type, for instance.

What computer languages are the hardest to learn (for a C speaker?). How does the design of the language influence the thoughts one has or can easily express in that language? (We know it does matter, Whorf or no Whorf!)
