Because integrals implicitly convert to characters of same
width (byte -> char, short -> wchar, int -> dchar).
Despite char.min > byte.min, char.max < byte.max. Anyway,
appending an integer is inconsistent because concatenation is not
allowed:
int n;
string s;
s = "" ~ n; //error
s ~= n; // ok!
This is the same for dchar instead of int.
This is also a problem for overloading:
alias foo = (char c) => 1;
alias foo = (int i) => 4;
static assert(foo(7) == 4); // fails
I would like to see some small changes to mitigate against things
like this, even if we can't agree to prevent the conversion
overall. It would be nice if we filed a bug as a rallying point
for ideas on this issue.
