-- Demonstrate any other kinds of string comparisons that the language provides, particularly as it relates to your type system. For example, you might demonstrate the difference between generic/polymorphic comparison and coercive/allomorphic comparison if your language supports such a distinction.
-- When comparing the right object is coerced into the same type as the object left from the operator. This implicit coercion enables to compare integers with strings (containining integer values).
set s1 to "3"
set int1 to 2
if s1 < int1 then
-- comparison is lexically
end if
if int1 < s1 then
-- comparison is numeric
