Would there be interest in having more idiomatic versions of the character check functions (from cctype & cwctype)?

Example
Replace
"int std::islower(int ch)" and "int std::iswlower(std::wint_t ch)"
With
"bool std::is_lower(char ch)" and "bool std::is_lower(wchar_t ch)"

Using overloads allows use in a more generic way.
The implementation could call the C function (in the correct way).
