list.head and list.tail use Ranges as examples

[JJ]

The problem

This example:

say ^10 .head(5);      # OUTPUT: «(0 1 2 3 4)␤» 
say ^∞ .head(5);       # OUTPUT: «(0 1 2 3 4)␤» 
say ^10 .head;         # OUTPUT: «0␤» 
say ^∞ .head;          # OUTPUT: «0␤» 

And the equivalent for tail use Ranges, not List. They actually be calling Any.head and Any.tail which, for the time being, are not documented.

Suggestions

Document Any.head and Any.tail, and fix those examples.
