Re: Sort on linkedlists with double values (inside main list)

If you have only two dimensions, you'll get away with your solution
for small integer coordinate values. Here is a counter example with
integers:

println ([[x:  1, y: 69273666],  [x: 69273666, y: 1]].sort{[it.x,
it.y]}) // broken
println ([[x:  1, y: 69273666],  [x: 69273666, y: 1]].sort{ a, b ->
a.x == b.x ? a.y <=> b.y : a.x <=> b.x }) // works
