Comparing integer signed and unsigned variants will result in error:

import std.variant;

void main()
{
  auto a = 11;
  auto b = 10u;	
  assert(a > b);
	
  Variant va = 11;
  Variant vb = 10u;
  assert(va > vb); //error
	
}

std.variant.VariantException@std/variant.d(1309): Variant: attempting to use incompatible types int and uint

Is this intended behaviour? I'm asking because the rest of arithmetic/equality operations are working as expected, only opCmp throws.
