Using std.algorithm.sort(a,b,c,d,e) I get the error message :

core.exception.AssertError@C:\dmd\windows\bin\..\..\src\phobos\std\algorithm.d(1
0350): Predicate for isSorted is not antisymmetric. Both pred(a, b) and pred(b,
a) are true for a=Tuple!(float, int, uint[], int, uint[])(-7.56963e-05, 17, [585
105407, 512], 1041, [2732589055, 0]) and b=Tuple!(float, int, uint[], int, uint[
])(-7.56963e-05, 17, [2732589055, 0], 1105, [585105407, 512]) in positions 25182
 and 25183

I am using the default predicate so is it a bug?

But isn't std.algorithm.sort accepting only one argument?

Looks like a bad bug:

void main()
{
     uint[] a = [0x22_DF_FF_FF];
     uint[] b = [0xA2_DF_FF_FF];
     assert(!(a < b && b < a)); /* fails */
}

Sorry, it's sort(zip(a,b,c,d,e))

Is it chain you are after to concatenate the objects and sort them together?

http://dlang.org/phobos/std_range.html#.chain

You'd need to cast them all to the same type.

This looks pretty serious. Please file a bug:
