import std.stdio;
string s(string t1, string t2){
        return "writeln(\"" ~ t1 ~ " " ~ t2 ~ " \"~ typeof(true ? cast(" ~ t1 ~
") 1 : cast(" ~ t2 ~ ") 1).stringof);\n";
}
void main()
{
        mixin(s("ifloat","double"));
}


result of above code doesn't make sense to me. if something like

auto a = true ? 1i : 1;

is allowed, it seems the result type should be complex; not imaginary, and not
real.

I'm also curious why combining a char with a wchar or some such results in a
uint

char and wchar both implicitly convert to int, so that is expected behavior.

The common type of float and ifloat etc should of course be cfloat.  etc

Imaginary and complex numbers are going away.
