Actually theres a third argument, too.  Is it really an error, or a 
branch?  I would argue is the latter.  Its not so much that the absence 
thunk is there 'in case something goes wrong'.  Its more like those 
operators are acting as conditionals, returning one value when the 
collection can provide it, and evaluating the thunk if it cannot.
This is the semantic argument.
