Comparisons

Assuming the user tries one of the following statements...

string < number;

string > number;

string <= number;

string >= number;

... - or any other comparison that doesn't contain either two strings or two numbers - the return value of < and > will always be false while <= and >= will always result in true. I think the comparison of a number and a string should either result in a runtime error or in the comparison of

number < #string;

or whatever comparator is used.

The Lua Reference Manual said that the code of the lt operator looks like this:

     function lt_event (op1, op2)
       if type(op1) == "number" and type(op2) == "number" then
         return op1 < op2   -- numeric comparison
       elseif type(op1) == "string" and type(op2) == "string" then
         return op1 < op2   -- lexicographic comparison
       else
         local h = getbinhandler(op1, op2, "__lt")
         if h then
           return not not h(op1, op2)
         else
           error(···)
         end
       end
     end
