Worse than useless; it doesn't even behave as you would expect.

import std.stdio;

void main()
{
        auto a = -1;
        writeln(+a); //Prints -1
        writeln(-a); //Prints  1
}

At least unary - does something.

I like to use the unary plus *in some cases* of tabular data, to 
reinforce the signess. Something like this:

auto foo = [
    +1234,
    -5678,
    -4242,
    +9999
];
