Here is a quick example demonstrating `cc-cmps ability to compare values of different types. The comparison is based on the Unicode value of each character in the string converted to lower case. Exception: Even though (== ##NaN x) is false for all If the vector already has sufficient memory to accommodate all characters in the string, we can even pass the input iterator to the beginning of the vector to the std::copy algorithm, as Clojure AOT Compilation. string converted to lower case.
