I am not aware of any difference in behavior. I have never used the
string.len form, which look to me like an old Lua 5.0 function.
But I checked in the manual, and was surprised to note that it is not
marked as deprecated, not even in Lua 5.2.
To Roberto: is this function still maintained for compatibility, or
for another reason ?
