C++ has the same with implicit constructors, generally considered to be a footgun that should be disabled with the explicit-keyword unless such a cast makes sense, implicit constructors are otherwise the default. For example vector has a constructor with takes integer size argument, if it wasn't explicit you could accidentally do vector v = {10} which would construct a vector with 10 empty elements, instead of one element with value 10. This also has to do with the ambigous curly brace syntax in c++.
