void main() {
    dchar c = 'A';
    dstring s0 = "bcd";  // OK
    auto s1 = c ~ s0;    // OK
    auto s2 = c ~ "bcd"; // Error, bad.
    string s3 = "bcd";
    auto s4 = c ~ s3; // Error, good.
}


dmd 2.063alpha gives:

temp.d(5): Error: incompatible types for ((c) ~ ("bcd")): 'dchar' and 'string'
temp.d(7): Error: incompatible types for ((c) ~ (s3)): 'dchar' and 'string'


The line of s4 is an expected error. But I think the error with s2 should not
happen.
