Re: Canonical way to sort an iterator or make it into an array/list

If system.cmp is not defined for T, T is a custom type, and you have to provide 
a custom cmp function anyway. In most cases though system.cmp is defined, so I 
can't see why it shouldn't be implied by default. The compilation will crash 
when no cmp is set for custom types, but it should crash, it's valid and 
expected behavior.
