It allows for a form of type substitution. I can write a function like:
function copy(to,from)
local data = from:read(8192)
if data then
to:write(data)
return copy(to,from)
end
end
and as long as the from parameter supports read() and the to parameter
supports write(), it won't really matter if to and from aren't a FILE*
userdata.
