Problem with using std.math: abs and std.complex: abs at the same time

[berni via Digitalmars-d-learn]

The following code doesn't compile:

import std.stdio;
void main()
{
   import std.complex: abs, complex;
   import std.math: abs;

   auto a = complex(1.0,1.0);
   auto b = 1.0;

   writeln(abs(a));
   writeln(abs(b));
}

The error message depends on the order of the two import 
statements. Seems like the second import is actually ignored.

I hoped for a mechanism similar to overloading, which makes the 
compiler decide, which "abs" to use, depending on the type of the 
operand. Is there a way to do this? (As the code appears inside a 
template, something like std.math.abs() with static import 
doesn't work out well.)
