I agree, the error should contain better reasoning as to why the 
function cannot be deduced. Since Phobos uses templates pretty 
heavily, and sometimes has a decent set of pre-conditions, 
tracking down which condition exactly is failing is hard. 
Printing the template condition and the expression in it that 
caused the instantiation to fail would be tremendously helpful!
