Here's the utility module:

//create function overload group
public import std.algorithm : cmp;
public import std.math : cmp;
auto cmp(A, B)(in A a, in B b)
if(!(isInputRange!A && isInputRange!B) //exclude
std.algorithm.cmp
&& !(isFloatingPoint!A && isFloatingPoint!B)) //exclude
std.math.cmp
{
return a==b ? 0 : a<b ? -1 : 1; //last resort
}
```
The other module that publishes the utility module:
```d
module testcmpmodule2;
public import std.algorithm, testcmpmodule, std.stdio;
void w(A...)(in A a){ writeln(a); }
```
What's happening here is that the overload set created by the
utility module is conflicting with the overload set created by
the `public import` in `testcmpmodule2`. If you remove
`std.algorithm` from `testcmpmodule2`'s `public import` line, the
code compiles successfully.
