Thank you Adam,

Question, why a function can not be nothrow if I catch in the 
body?

void foo() nothrow {
     import std.utf : validate, UTFException;
     try {
         validate("a");
     }
     catch(UTFException){
     }
}
Error: function `std.utf.validate!string.validate` is not 
`nothrow`
Error: `nothrow` function `foo` may throw
