Interesting question.  How's this?

import std.stdio;

template touint(char[] T)
{
     static assert(T.length==4, "Integer constants must be of length 4");
     const uint touint =
         (cast(char)T[0] << 24)|
         (cast(char)T[1] << 16)|
         (cast(char)T[2] << 8)|
         (cast(char)T[3]);
}

enum
{
     kSomeConstantValue = touint!("xyzz")
}

void main()
{
     writefln("%x", kSomeConstantValue);
}
