Frankly, I think much of this is because of the level of the discussion.

Suppose you try to multiply an integer times a URI. Do you want that error 
to be caught? Suppose you want a sorted list of numbers - do you want to 
sort them numerically rather than lexically? If so, types are good. Yes, 
whoever implemented the system had to think to make that happen. We have 
descriptions of the thinking implementors will have to do.

Has the strong static typing of Java gotten in your way as a programmer?
