This can be defined instead as:
alias reduce!"a+b" sum;

But then you have to write:

    sum(sequence, 0)

which is very unintuitive.

This works:

import std.stdio;
import std.algorithm;

alias reduce!"a+b" sum;

auto sumOfSquares( R )( R range ) {
     return sum( map!"a*a"( range ) );
}

void main()
{
    writeln(sumOfSquares([1,2,3]));
}
