This is the root of the problem.  Character types should never 
have been implicitly convertible to/from arithmetic integral 
types in the first place.

Occasionally, it's useful, but in most cases, it just causes 
bugs - especially when you consider stuff like appending to a 
string.

I remember a fairly old defect, or maybe it was just a post in 
the Learn forum. Doing "string" ~ 0 would append '\0' to a 
string, because the int was auto-converted to a char. This still 
works today:

import std.stdio;
void main()
{
    string msg = "Hello" ~ 0 ~ " D" ~ '\0';
    writeln(msg);
    writeln(cast(ubyte[])msg);
    writeln(cast(ubyte[])"Hello D");
}
