In an ideal world, explicit conversions in C++ would be the default, especially between fundamental types, perhaps requiring an implicit keyword for implicit type conversions.

1) Specifies that a constructor or conversion function (since C++11) or deduction guide (since C++17) is explicit, that is, it cannot be used for implicit conversions and copy-initialization. 2) The explicit specifier may be used with a constant expression.
