What you need is to create an overload of toString that takes a

I want to sort a two-dimensional ndslice by its columns according
to some predefined predicate.
What I mean is _not_ sorting the contents of each column
individually, but instead to reorder the entire columns of the
matrix so that they are sorted according to some "greater than"
function.

Hello.
I need subtype uint to store ipv4 address.
It should be like ordinary uint,
except conversion to string with %s format.
My try https://run.dlang.io/is/fwTc0H failed on last assert:
```

{
private uint ip;
alias ip this;
string toString()
